True or false: If an ideal gas is throttled in a gate valve from a higher pressure P1 to a lower pressure P2, then the exit temperature T2 is higher than the inlet temperature T1. Why?

Expert Solution

FALSE

In throttling process the fluid flow is restricted by partially closed valve. During the process there is no change in enthalphy. As in the case of real fluids id we restricted the area then there will be less area for fluid to escape and tgis leads to collisions between atoms most rapidly and this collisions yield a temperature rise after throttling.

But in the case of idea gas the molecules occupy negligible space and there are no interactions between them so there are no collisions this leads to temperature decrease after throttling.exit temperature is less than inlet temperature for only ideal gases.

An ideal gas with Cp = 2.5R at 298 K and 5.00 bar is adiabatically throttled to 1.00 bar. If the flow rate of gas is 1.71 mol/s, and the surroundings are at a temperature of 3°C, what is the rate of lost work, in kW? Please give your answer to 3 SF, and be very careful with units.

One method for reducing the pumping work in throttled spark-ignition engines is early intake valve closing (EIVC). With EIVC, the inlet manifold is held at a pressure pi, which is higher than the normal engine intake pressure pi*. The intake valve closes during the intake stroke. The trapped fresh charge and residual is then expanded to the normal cycle (lower) intake pressure, pi*. You can assume that both cycles have the same mass of gas in the cylinder, temperature and...
