You go on a road trip to escape the cold winter days of Kirkland Lake, Ontario to the warm beaches of Moonbeam, Ontario. Since it is a long drive and you are leaving early in the morning, you make sure to check the tire pressure and make sure it is at the recommended level. At lunchtime, you stop for gas and decide to check your car's tire pressure again. You also notice that the tires seem to be a little bit larger than when you left. The driver's manual suggests a pressure between 205 and 220 kPa. Knowing that the tires heat up while driving; do you expect your reading to be high, low or the same as the recommended tire pressure? Why? Since you plan on staying in Moonbeam a while to see the sights, you think it would be best to adjust your tire pressure. What adjustments should be made to your tires? Should you make these adjustments as soon as you arrive, or the following day?

Please read the project 2 description, then write down the solution strategy answer should be 100 words only The project 2 descriptions is shown as follows: There are three tanks as shown in Figure 1. Tank T1 initially contains 40 gals of water in which 16.98 lb of salt is dissolved. Tank T2 initially contains 40 gals of water and 3.92 lb of salt. Tank T3 initially contains 40 gals of water and 7.13 lb of salt. The inflow into T1 is 2 gal/min pure water from the outside and 2 gal/min brine from T2. The outflow from T1 to T2 is 4 gal/min.The inflow into T2 is 4 gal/min from T1 and 2 gal/min from T3. The outflow from T2 to T1 is 2 gal/min and from T2 to T3 is 4 gal/min. The inflow into T3 is 4 gal/min from T2. The outflow from T3 to T2 is 2 gal/min and from T3 to outside is 2 gal/min, as shown in the figure. The mixtures are kept uniform by stirring. Find and plot the salt contents y1(t), y2(t), and y3(t) in T1, T2, and T3, respectively

This is an engineering problem and not a writing assignment. Please Do Not Reject. I had other engineering tutors on bartleby help me with problems similar to this one. This problem must be presented in a logical order showing the necessary steps used to arrive at an answer. Each homework problem should have the following items unless otherwise stated in the problem: a. Known: State briefly what is known about the problem. b. Schematic: Draw a schematic of the physical system or control volume. c. Assumptions: List all necessary assumptions used to complete the problem. d. Properties: Identify the source of property values not given to you in the problem. Most sources will be from a table in the textbook (i.e. Table A-4). e. Find: State what must be found. f. Analysis: Start your analysis with any necessary equations. Develop your analysis as completely as possible before inserting values and performing the calculations. Draw a box around your answers and include units and follow an…

Group Problem: You are planning to build a log cabin in Northern Minnesota on a remote hill with a beautiful view of the setting sun. You will drag the logs up a long sometimes rocky hill to the building site by means of a rope attached to a winch. You will need a rope for this job so you aim to know how much weight the rope would safely support. You are operating on a tight budget so matching the rope strength would be a cost saver. You know that the logs are heavy, and estimate the heaviest as 1,000 lbs. From maps you verify the hill is steeped at an angle of = 70° with respect to the vertical, and you estimate a coefficient of kinetic friction between a log and the earthen hill as 0.5. When pulling a log you will ensure that the uphill acceleration is never more than 3.0 ft/s². The maximum recommended load is th of the nominal strength for the ropes considered as stated on the product labels, you have three ropes in mind: 12 kN, 18 kN, & 24 kN. Which one of these three rope…

XYZ Company Ltd has consulted your firm Zig-Zag Energy over an intention to generate electricity in Ghana. Being the senior project engineer for Zig-Zag Energy, management has asked you to prepare a detailed technical report in respect to the project. a) Discuss the major factors to take into consideration when consulting on such projects.                                                                                                           A tank containing air is stirred by a paddle wheel. The work input to the paddle wheels is 2000KJ and the heat transferred to the surrounding from the tank is 6000KJ. b) Determine the change in the internal energy of the system                                              There has been a sharp differences between the board of Blue-Blue Energy over which of the energy sources (hydroelectric power plant-HEP and Coal fired plant) is best for power generation.

as per your policy, customer service from bartley stated since you took a incomplete question and answered it instead of questions that actually need answering.    you owe me my questions and not to only solve one question, kindly solve all 3. And when i end up switching to CHEG not only will i be posting this on my vlog and social media i will also be contacting BBB and i will make sure to find out whos the special kid behind answering and trolling me ((:   kindly answer all 3 , thanks

hints: The flask will be filled with water (at a constant rate of 500 gallons per minute). It will take me exactly 10 minutes to escape from the chains. The diameter of the tank at 1 foot intervals. I am 5 feet 9 inches tall, and I'm pretty skinny so that you can ignore both my volume and the volume of the stool in your analysis. A gallon is equal to 0.13368 cubic feet.  You can think of the volume and the height of the water as functions of time. You can easily find an expression for V (t), and then use your expression for volume in terms of height to solve for h(t). after 10 minutes amount of water in the tank=66.84 ft3 t=69.3 minutes h(t)=e66.84t/100?  -1 h(10)=e66.84(10)/100?  -1=7.39 ft  Height of stool=1.64 ft Height of water in the tank=7.39 ft Questions: show work How fast is the water rising?  I would like to know how long I will have to hold my breath during the last part of the stunt.

Recall the discussion on spacecraft from the chapter opener. The following problems consider a rocket launch from Earth’s surface. The force of gravity on the rocket is given by F(d)=−mk/d2, where m is the mass of the rocket, d is the distance of the rocket from the center of Earth, and k is a constant. 172.  As the rocket travels away from Earth’s surface, there is a distance D where the rocket sheds some of its mass, since it no longer needs the excess fuel storage. We can write this function as F(d)=⎨(−m↓1 k / d^2) if d < D                                                                                  (−m↓2 k / d^2) if d ≥ D Is there a D value such that this function is continuous, assuming m1≠m2?
