Consider a control volume (OPEN system) in which air (cp=1004.5 J/kgK, cV = 717.5 J/kgK) flows from an inlet port 'in' to an outlet port 'out. The heat per unit mass TRANSFERRED TO the system is Q=5000 J/kg, the specific work DONE ON the system is Li=1000 J/kg. The air inlet temperature is t =30.00°C, the air inlet speed is C =10 m/s, the air outlet speed is c=50 m/s. By neglecting the gravitational potential energy variation, the air outlet temperature tt is: O (A) 33.90 °C (B) 36.69°C O (C) 34.78°c O (D) 32.79°c

Transcribed Image Text:Consider a control volume (OPEN system) in which air (cp=1004.5 J/kgK, cv = 717.5 J/kgkK) flows from an inlet port 'in' to an outlet
port 'out. The heat per unit mass TRANSFERRED TO the system is Q=5000 J/kg, the specific work DONE ON the system is
Li=1000 J/kg. The air inlet temperature is t=30.00°C, the air inlet speed is c =10 m/s, the air outlet speed is c50 m/s.
By neglecting the gravitational potential energy variation, the air outlet temperature t is:
O (A) 33.90 °C
O (B) 36.69°C
O (C) 34.78°CC
O (D) 32.79°c
