9-99 A gas turbine for an automobile is designed with a regenerator. Air enters the compressor of this engine at 100 kPa and 30°C. The compressor pressure ratio is 10; the maximum cycle temperature is 800°C; and the cold air stream leaves the regenerator 10°C cooler than the hot air stream at the inlet of the regenerator. Assuming both the compressor and the tur- bine to be isentropic, determine the rates of heat addition and rejection for this cycle when it produces 115 kW. Use con- stant specific heats at room temperature. Answers: 258 kW, 143 kW

You have a tank that is 0.01 m^3 and is initially evacuated. You then hook this up to a line that supplies N2 at a pressure of P_1 = 5 bar and a T_1 = 350 K. The tank fills adiabatically (you can assume there is no heat flow to the walls of the tank), and the filling ends when no more N2 flows into the tank. Find a) the final pressure of the gas in the tank, and b) the final temperature of the gas in the tank. You can assume N2 is an ideal gas with a CP* = 29 J/mol K. NOTE: Mainly I am confused on how the evacuated tank factors into the work for b). What I did was use the ideal gas formula to find a value for N2*T2 (601.395) but I am no longer certain how to continue in the work. I was assuming the practice question had meant the temperature of the tank was 0 initially but it leads to a negative mole value. For a) I got 5 bar, arguing the flow would stop when the pressure of tank and line are equal
