Answer all parts correct and complete to get 100% feedback!!

R134a is heated in a pipe as shown below.

Find

(i) Exit velocity under constant area and mass flow rate (mass flow rate = 1.72 kg/s).

(ii) Rate of heat lost to the surroundings.

Enter:

Pin=400kPa

Tin=30C

Vin=50m/s

Exit:

Pin=280kPa

Tin = 60 C

Vout =?
