An inventor claims to have developed a Lenoir engine with an isentropic compression ratio of 8.00 to 1 that produces a combustion temperature of 1500.°C when the intake temperature is 20.0°C.
Assuming k = 1.40 and that the engine operates on a cold ASC, show whether or not the inventor's claim is possible.
Determine the currents in the circuit below. For consistency please assume the currents are as drawn belo. Develop three equations, but do not solve for them.
