Q22. 0.25 kg of air at pressure of 140 kN/m2 occupies 0.15 m' and from this condition it is compressed to 1.4MN/m2 according to the law PV1.25 = C. And then heated at constant volume to pressure of 2 MN/m2. Calculate the work, heat transfer and the change of entropy during these processes. Take, C, 1.006 kJ/kg K, R-0.287 kJ/kg K. %3D

6. Please help me solve this mech. engineering question
I need the answer as soon as possible
How would I solve this? I am confusion.
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.
Pls heelpBlank is the time-honored tool for describing geometry
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.
