(e) Water is entering a heated tube at mass flow rate of 1.2 kg/s. The temperature at the inlet 20°C and at the outlet is 80°C. Assume the surface temperature of the tube is 100°C. The convectic coefficient of the water flow is 28 W/m².°c. The specific heat and density of water can be assumed t be 4180 J/kg-°C and 990 kg/m³. What is the rate of heat transfer to water during this process?
