Need full solution to understand the problem. Thank you

3. A wind tunnel is considered to be a steady-state operation, the system receives one hundred fifty pound- mass per minute of air at 210 psf, and 210 degrees Fahrenheit. The fluid is discharged from a point five meters above the datum, reference point at 4,255 psf and 450 degrees Fahrenheit. Assuming that the velocity found at the inlet is 7,225 feet per minute and the Heat supplied is 520 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 8 minutes? (20 pts)
