Carbon dioxide gas is compressed at steady state from a pressure of 18 lb/in² and a temperature of 32°F to a pressure of 50 lb/in² and a temperature of 120°F. The gas enters the compressor with a velocity of 30 ft/s and exits with a velocity of 80 ft/s. The mass flow rate is 4000 lb/hr. The magnitude of the heat transfer rate from the compressor to its surroundings is 5% of the compressor power input. Use the ideal gas model with cp = 0.21 Btu/lb-ºR and neglect potential energy effects. Determine the flow area at the inlet, in ft2, and the power required by the compressor to work, in horsepower.

I am getting lost in this practice problem for thermodynamics - thank you! Air at 100 kPa and 280K is compressed steadily to 600 kPa and 400K in an air compressor. The mass flow rate of air through the compressor is 0.02 kg/s and the compressor a heat loss of 16 kJ/kg from the compressor occurs. Assuming steady state steady flow conditions and ideal gas behavior (with constant specific heats, Cp=1.009 kJ/kgK, R=0.287 kJ/kgK, determine: a) The necessary power in put to the compressor(kW).b) The volumetric flow rate of air at the exit of the compressor (m3/s).
A mixing vessel initially contains 4133.3 lb of liquid fluid. The vessel is fitted with two inlet pipes, one delivering hot fluid at a mass flow rate of 0.768 lb/sec and the other delivering cold flu'd at a mass flow rate of 0.439 lb/sec. Fluid exits through a single pipe at a mass flow rate of 1.133 lb/sec. Calculate the amount of fluid, in lb, in the tank after 25 minutes.
