where P and P1 are the measured and atmospheric pressures in psia, Cp is the calibration constant in psia/volts, V is the transducer voltage, and V0 is the offset voltage.
RESULTS AND DISCUSSION To convert the measured voltages to pressures, we first determined the calibration constants of transducers 2 and 3 for each of the trials ranging from 6 to 14 psig. To do this, we calculated the measured shock wave velocity for each trial by dividing the distance between transducers 2 and 3 (0.548 m) by the measured time difference between the peak measured voltages. Next, assuming T = 70° F and γ = 1.4 (for air), we calculated the speed of sound and Mach number using equations 2 and 3. We used this measured Mach number

Calibration constants, in units of psia/volt, for transducers 2 and 3 at different driver conditions.
The results show that the calibration constants vary slightly based on the driver pressure due to the different gain settings used. However, the calibration constants change dramatically if the shock tube is closed, or if a different driver gas is used.
Using the calculated calibration constants, we converted the measured voltage data to absolute pressure data. The pressure data for driver pressures of 6, 10, and 14 psig have been plotted versus time in Figures 2-4 below.
Figures 2-4. Pressure transducer data for driver pressures of 6, 10, and 14 psig in an open shock tube.
These plots clearly show an identical trend across all three driver pressures – a discontinuous rise in pressure in wake of the shock wave followed by a continuous drop in pressure below Patm = 14.7 psi in wake of the reflected rarefaction wave before finally re-pressurizing back to atmospheric pressure. In addition, as the driver pressure increased, the magnitude of the peak and trough pressures, P2 and P6,

In Figure 8b for transducer 3, which is closer to the right wall, we see a discontinuous increase from P1 to P2 in wake of the shock wave, as expected, but also an additional discontinuous increase from P2 to P5 due to the reflected shock wave. Afterwards, we notice a continuous drop in the pressure from P5 to P1 due to the reflected rarefaction wave. However, in Figure 8a for transducer 2, we see that pressure drop due to the reflected rarefaction wave occurs before the pressure rise due to the reflected shock wave. This results in a strange feature in the graph just to the left of t = 0.01s, in which the pressure begins to drop continuously, but halfway through rises discontinuously before dropping continuously once again. Due to these reflection related phenomena, the pressure traces (for transducers 2 and 3) for closed condition not only look very different from each other, but also different when compared to the open
P2 which is full annealing of the material after the operation P1, an operation P3 which is mechanical processing the material after operation P2, and an operation P4 which is soft annealing the material after operation P3.

The purpose of this experiment is to measure the speed of sound in air and to determine the effects of frequency on the speed of sound.
A Newtonian fluid is a fluid that exhibits constant viscosity regardless of any external stress applied to it, like mixing or a sudden application of force. Like water; this flows in the same direction regardless of whether it’s left alone or agitated. A Newtonian fluid, by definition, can only be affected by pressure and temperature together, or temperature, but not pressure on its own.
1. Read `Spotlight on Management` on pages 133-149 and the practice lesson `The Real World` on page 152. Please discuss the following questions in detail. Your response to each question should consist of: a minimum word count of 250 words and at least three (3) scholarly sources (1 resource can be the textbook):
Health and Safety at Work Act (1974): This is the main piece of health and safety legislation in the UK. This sets out a base of guidelines and principles for employers and helps secure the health, safety and welfare of people at work, control handling of dangerous/harmful storage substances, and to control dangerous chemicals or gases that could find their way into the atmosphere. This legislation is important for the job of a PE teacher as there is a lot of various sporting equipment that the teacher has the authority to use, and therefore some of this equipment could be dangerous, therefore this act means PE teachers and other teachers have to take special care, warn others and show them how to use the equipment properly (such as children),
It is important that when there are suspicions about abuse or neglect occurring then they should be followed up and ensured the relevant people know so can therefore deal with the issue and make sure no allegation is ignored. I am going to discuss different strategies used to respond to suspected abuse and neglect. You must follow safeguarding policies and procedures, finding what is involved in the policies and procedures could involve researching on the internet or looking in a handbook given to you when you began work there. If the abuse was suspected another way you could respond could include informing the police or a safeguarding officer to carry out an investigation and look into it further.
The requirements of the skills and qualities are needed for my chosen health care professional from Task 4. However, the skills for the health care professional (GP) is what the health care professional (GP) has learnt like their behaviour or knowledge, such as good communication with the patients; this is a method to help develop an effectively good/positive relationship with the GP and the client, actions like body language will help make a good/positive relationship with the GP and client, so such as eye contact, attention, happiness (like showing an emotion/smile between the client) and so on will develop an effective relationship between the client and the reader; this will make the client trust the GP that will make them tell more personal information and feelings with the GP; this can help the GP on maintaining information on the client and get to know more about the client. Also, another skill that the GP is required to have is having a master knowledge between situations with the GP and the client, like the GP would know what actions to do and understand. But, the GP will need to go to university to learn knowledge in certain situations with the client, such as certain illnesses with
There is a huge range of ways that we can use to take an individual’s thoughts, opinions and circumstances into account, when care planning. An example of this is, an assessment for an individual, who is going through the planning process of an Education Health Care Plan (EHCP). He/she will be assessed by an Educational Psychologists and other health and social care professionals, who will write up their own report. During this process they are expected to ask the individual what he/she would want from the EHCP. Another way of empowering an individual and allowing them to express their feelings and opinions freely is by implementing The Human Rights Act (1998), using the specific section Article 10, “Freedom of Expression” .
Recommendations P4.1, P4.2, To promote Baby B development as much as possible making her feel included in activities such as when doing a focused activity with water, sand, dough, paint or crayons etc and making sure she explores and succeeds at own pace along with the other children Establish routines with Baby B, this can be when events are predictable, when they happen in approximately the same way at approximately the same time each day, this will make Baby B feel safe, secure, confident and in control of her world. Books reading, then songs and then snack time, she will gradually understand what will happen next and can prepare for those changes. If day-to-day events seem to occur randomly, it can cause children a lot of anxiety. If life
P2.1- Evaluating the impacts of the principles of health, safety and security legislation on travel and tourism sector- The main objective of health and safety regulations is to make sure that the working environment is safe and secure. Under the tourism sector, the country’s goal is to ensure the safe accommodation and such other services by setting out the duties and determining liabilities. The Health and Safety at Work (HSWA 1974) lays out the regulations making it mandatory for the employers to perform their duties towards the employees and the members of the public.
In this assignment I am going to be explaining the factors that may influence communication and interpersonal in health and social care environments and also I am going to be explaining the strategies used in health and social care environments to overcome barriers to effective communication and interpersonal interactions. I will be including sensory deprivation, foreign language, jargon, slang, dialect, acronyms, cultural differences, distress, emotional difficulties, health issues and environmental problems, misinterpretation of message, aggression, assertion and how they can be overcome.
In chapter four, Nash attempt to look at the logical fallacies of Hick’s position. He examines other pluralist claims against exclusivism and its supposed outdated reasoning. The other pluralist that he cites is W.C. Smith, and Paul Knitter. Nash presents these claims by talking about the basic understanding of logic. Nash main point is to point out truth and validity of the very basic principles of this argument. He points out several rules of logic, in addition, he points out the idea of truth and its ties to propositions. Then he moves on to differentiate truth and logic with religious claims: “while belief certainly includes more than mental assent to proposition, belief always includes believing something, and that something is a proposition.” It is imperative to note, just like any other claim religion should be looked at in the same way. Nash disagrees with W.C. Smith also. Nash noted, “Smith’s way of handling religious “truth” might appear to solve a serious problem for pluralists (the problem created by their apparent rejection of logic), it only raises new and equally troubling questions.” Therefore, pluralist like these two men that downplays logic and truth will never be able to support they beliefs.
* The relevance of this experiment is similar to understanding a real airplane. Paper airplane models are derived from an actual plane these days. The design of an airplane has so much to do with distance, hang time, speed, and many other factors. Understanding the models I have chosen to make help me
