Refrigerant 134a flows through a horizontal pipe. Inlet: T = 40C P = 280 kPa 1 Outlet: T = 40C P = 240 kPa

WHAT IS THE CORRECT ANSWER?

A) 5.21

B) -15

C) 57.6

D) -62.1

E) 0.37

Refrigerant 134a flows through a horizontal pipe. Inlet: T = 40C P = 280 kPa 1 Outlet: T = 40C P = 240 kPa The mass flow rate is 0.5 kg/s. Kinetic and potential energy effects can be neglected. Calculate the heat transfer rate, in kW, between the pipe and its surroundings.
