Carbon dioxide gas enters a well-insulated diffuser at 20 lbf/in.2 , 500R, with a velocity of 800 ft/s through a flow area of 1.4 in.2 At the exit, the flow area is 30 times the inlet area, and the velocity is 20 ft/s. The potential energy change from inlet to exit is negligible. For steady-state operation, determine the exit temperature, in R, the exit pressure, in lbf/in.2 , and the mass flow rate, in lb/s.
