In an open system, 500 kg/h of air is being compressed from 100 kPa at  280 K to 600 kPa and 400 K. The air enters the compressor at a linear  velocity of 50 m/s and leaves at a velocity of 100 m/s. The power required  for the compressor is 50 kW, and the heat loss from the turbine is  estimated to be 10,000 kJ/h. Determine the specific enthalpy change that  associated with the process. The process is in steady state and has no  change in its mass flow. (1 kW = 3600 kJ/h)

Question

In an open system, 500 kg/h of air is being compressed from 100 kPa at 
280 K to 600 kPa and 400 K. The air enters the compressor at a linear 
velocity of 50 m/s and leaves at a velocity of 100 m/s. The power required 
for the compressor is 50 kW, and the heat loss from the turbine is 
estimated to be 10,000 kJ/h. Determine the specific enthalpy change that 
associated with the process. The process is in steady state and has no 
change in its mass flow. (1 kW = 3600 kJ/h)
