Question

Consider a flow of water in a cylinder maintained at constant temperature of 100° C, the
diameter of the cylinder is 50 mm and the length of the tube is 6 m. The inlet and the
outlet temperature of the water is T = 15° C and T = 57°C. Find the average heat
transfer coefficient associated with the flow of water. Mass flow rate is 0.25 kg/s and
C = 4.178 kJ/kg.K.
(A)850 W/m².K
(B 650 W/m².K.
(C)755 W/m².K
(D) 725 W/m².K​
