Question

A steady flow system receives 4.56Kg per minute of a fluid where P1 = 137.90 Kpa, v1 = 0.0388 m3/Kg, V1 = 122 m/s, u1 = 17.16 KJ/Kg. The fluid leaves the system at a boundary where P2 = 551.6 Kpa, v2 = 0.193 m3/Kg, , V2 = 183 m/s, u2 = 52.80 KJ/Kg. During the passage through the system, the fluid receives 3,000 J/s of Heat. Determine the work in watts

m = 4.56 kg/min pi =137.90 kPa
P2 =551.6 kPa
u = 17.16 kJ/kg
uz = 52.80 kJ/kg
Vị = 0.0388 m/kg
V2 = 0.193 m'/kg
V1 = 122 m/s
V2 = 183 m/s
Q = 3000J/s
w = ?
= 3 kJ/s
= 3 kW
Ein = Eout
u1 + wf1+ KE1 + Q = w + u2 + wf2 + KE2
