Asystem for heating water of an inlet temperature of 20 c passes through a thin tube having an inner diameter of 20 mm. a uniform heat generation rate of q” = 1.5x10^4 w/m2 is supplied to the tube surface. a water mass flow rate is 0.1 kg/s and heat transfer coefficient in the tube is 1500 w/m2.k. assure cp = 4179 j/kg. k. (a) what is the outlet water temperature? (a) what is the inner surface temperature of the tube?
