Water at an average temperature of 27C is flowing through a smooth 5.08-cm-ID pipe at a velocity

Question:

Water at an average temperature of 27°C is flowing through a smooth 5.08-cm-ID pipe at a velocity of 0.91 m/s. If the temperature at the inner surface of the pipe is 49°C, determine (a) the heat transfer coefficient,

(a) The rate of heat flow per meter of pipe,

(b) The bulk temperature rise per meter, and

GIVEN

Water flowing through a smooth pipe
