Then you need to contact your professor and get a clarification on the question.Ashley1nOnly said:My professor made it up
I think that's what the question is trying to tell us , that is that the work done to the gas is ##n2\pi l F## and since the chamber is thermally isolated and we assume the transfer to be instantaneous ##\Delta U+W=0## and from this to calculate the ##\Delta T## to answer perhaps e). But yes since it says the piston is fixed, don't know what crank is that that does work to the system. Also instantaneous transfer that takes n turns of a crank doesn't seem too orthological either...Nidum said:(2) This might be a garbled version of a similar question that I have come across before . In that there was a screw being driven by the crank and the action of the screw propelled the piston down through a cylinder . N turns of the screw with a known applied torque gave a value for work done .
The piston and crankshaft work together to convert the energy from the combustion of fuel into rotational motion, which is used to power the engine.
The temperature of the gas entering the cylinder can impact the efficiency of the combustion process, which can in turn affect the power output and overall performance of the engine.
The ideal temperature for gas entering the cylinder varies depending on factors such as the type of fuel and engine design. Generally, a higher temperature can lead to more efficient combustion, but there is a limit to how high the temperature can be before causing damage to the engine.
The temperature of gas entering the cylinder can be measured using various techniques, such as thermocouples or infrared sensors. These devices are typically placed near the intake valve or in the intake manifold to measure the temperature of the incoming air-fuel mixture.
Yes, the temperature of gas entering the cylinder can be controlled through various methods, such as adjusting the air-to-fuel ratio, using intercoolers or water injection, and changing the timing of the intake valve. These methods can help optimize the temperature for better engine performance and efficiency.
