COMPRESSOR PROBLEM
Compressors are used generally to increase the energy strength of incoming fluid streams, but they
generally require power-work/time input to operate.
# 1 Separate streams of air and water flow through the compressor and heat exchanger arrangement shown in the
figure below, where the mass rate m'1 varies from 0.5 kg/s to 2.5 kg/sec in increments of 0.5 kg/sec and T6=
50°C. Steady-state operating data are provided on the figure. Heat transfer with the surroundings can be
neglected, as can all kinetic and potential energy effects. The air is modeled as an ideal gas.
Determine:
(a) the total power provided for both compressors, in kW.
(b) the mass flow rate of the water, in kg/s.
c) the cost to operate the system.
