A Team of Engineers asked for an internal combustion engine to use it in a designed car. Your role is to describe the operation sequence of different types of available engines, explain their mechanical efficiency, and deliver a detailed technical report to show your approach in solving and discussing the following tasks and issues. You must follow the following steps to help the team: STEP 1 Describe the operational sequence of four-stroke spark ignition and four-stroke compression ignition engines with the aid of sketches by constructing simple sketch representing the operation and plotting the P-V diagrams for each process during the cycle to show the following: The input and output heat and net output work The air-fuel mixture intake and exhaust gasses The spark plug when it is in the active mode

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.

SHOW YOUR SOLUTIONS PLS, THANKS show me how you did it so I can understand, thank you. Pls answer both, this is my last tutor question, pls. thank you. (Porosity). A dry rock weighs 240 grams and has a bulk density of 2.4 grams per cubic centimeter. When saturated with pure water at room temperature (T=25°C), it weighs 250 grams. At room temperature, the specific volume of water is 1.00295 x10-3m3/kg. Calculate the porosity of the sample. (Permeability). A cylindrical core sample of 1 cm length and 1 cm2cross-section has upstream and downstream pressures of 2 atm and 1 atm, respectively, during steady state flow of water at 0.997 g/s at room temperature. Calculate the permeability of the core. Note: Water @ 25°C, viscosity = 1 cp, density of water = 0.997 g/cm3.
According to this flowchart, the Sun will become A. hotter and brighter in stage 2, then cooler and dimmer in stage 3 B. cooler and dimmer in stage 2, then hotter and brighter in stage 3 C. hotter and dimmer in stage 2, then cooler and brighter in stage 3 D. cooler and brighter in stage 2, then hotter and dimmer in stage 3
Problem: Insufferable Enlightenment era scientists are a lot like insufferable frat boys/sorority girls - they just cannot get enough of themselves. One of the most well-known "big brain" contests in their history was a Europe-wide challenge presented by a certain Swiss scientist called Johann Bernoulli (who already had his own solution so that he could pompously show off once the submissions came in). He asked the "leading minds of the world" the following: What is the curve along which a particle, under constant gravitational acceleration g, would descend from one arbitrary point to another within the fastest duration of time? Fancily called the brachistochrone problem (derived from the Greek word for just "shortest time"), Bernoulli's initial solution used the law of refraction as the result of applying the principle of least time to a light particle. Let's give this solution a shot ourselves. (a) Consider an initial point of (xo, 0), both parameterised by time t. Our goal is to…
Hi, can I please have some ideas of what sort of questions you would ask about this project? (The poster seen is meant as a review of what topic was picked and where the project is up to after a few weeks.)
Stuck need help! Problem is attached. please view attachment before answering. Really struggling with this concept. Please show all work so I can better understand ! Thank you so much.
