Air flow steadily at the rate of 0.95 kg/s through air compressor, entering at 7.5 m/s speed, 95 Kpaa pressure and 0.95 m3 /kg specific volume and leaving 20 m/s, 725 kpaa and 0.19 m3 /kg. the internal energy of the air leaving is 100 KJ/kg greater than that of the air entering. Cooling water in the compressor jacket absorbs heat from the air at the rate of 60 kJ/s. compute the steady flow work in kW

A wind tunnel is considered to be a steady-state operation, the system receives one hundred fifty pound- mass per minute of air at 285 psf, and 270 degrees Fahrenheit. The fluid is discharged from a point five meters above the datum/ reference point at 4,255 psf and 750 degrees Fahrenheit. Assuming that the velocity found at the inlet is 6,285 feet per minute and the Heat supplied is 580 BTU/min. During the process the density decreases by 15 percent and the internal energy is decreased by 1.05 horsepower. Determine the Work done in (a) Horsepower and BTU/s. (b) Considering the given on 3a, if the Work done is doubled, determine the Heat supplied during the process? (c) Considering the given on 3b, if Heat is doubled, what is the work done after 6 minutes?
