Question

A small turbine using compressed air has a power output of 100 W.

The enthalpy of the air at the inlet is 320 kJ/kg and the enthalpy at the outlet is 240 kJ/kg. Assume the process is adiabatic and the change in the kinetic energy is negligible. Compute the mass flow rate.

Answer 1

$\dot m=\frac{S_1-S_2}W=0.8~\frac{kg}s .$
