Air enters a length of constant area pipe with p1 = 490 kPa (abs), T1 = 450 K, and V1 = 130 m/s. The diameter of the pipe is 0.1 m. If 480 kW of energy is added to the air by frictionless heat transfer between sections (1) and (2), determine p2, T2, and V2.

Answer #1
Red boxes are for the properties of air taken from property table.
Answer is in the purple boxes.
your answer might slightly varry depending upon the air properties you take.
You might also see 103 multipled twice. One of them is to convert kW into Watt.Another is for kJ/ kgK to J/ kgK
