PROBLEM 2 Consider the arrangement shown in Fig. 1. For this setup the streams of air and water flow are separated, and the air is modelled as an ideal gas. The data for steady-state operation is shown in the figure. Assume that heat transfer to the surroundings can be neglected. Questions: Determine: (a) the total power required by both compressors, in kW (b) the velocity of the air at the exit of the nozzle, in m/s (c) the mass flow rate of the water, in kg/s (d) the power required by the pump, in kW
