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 C₂ = 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 Answers: A
