Air enters the compressor of a gas turbine power plant at a pressure of 100 kPa and a temperature of 25 ° C at a low speed, and at a pressure of 1 MPa and a temperature of 347 ° C, it exits at a speed of 90 m / s. With the cooling in the compressor, 1500 kJ of heat is lost from the air per minute. The power required to run the compressor is 250 kW. Find the air flow rate passing through the compressor in kg / s. Atmospheric air can be considered an ideal gas and fixed specific heat values ​​can be used. (R air = 0.287 kJ / kg.K; cp = 1.005 kJ / kg.K)
