Water is to be heated from 10°C to 80°C as it flows through a 2 cm internal diameter, 13 m long tube. The average flow rate of water is 5 L/min. Find average velocity of water and the convection heat transfer coefficient. The water is heated using an electric resistance heater (in the tube) which provides uniform heating throughout the surface of the tube. The outer diameter of the tube is well insulated, such that in steady operation all the heat generated in the heater is transferred to the water in the tube. Assume turbulent flow for Re > 5000 for this problem

Awall of 0.5m thickness is to be constructed from a material which has average thermal conductivity of 1.4 w/mk. the wall is to be insulated with a material having an average thermal conductivity of 0.35 w/mk so that heat loss per square meter shall not exceed 1450 w. assume inner wall surface temperature of 1200°c and outer surface temperature of the insulation to be 15°c. calculate the thickness of insulation required.
