Question 1: Water enters a tube (shown below) at a flow rate of 6 lit/min and an inlet temperature of 60°C. The convection coefficient and temperature at the external surface of the tube are set to 50 W/m°K and 10°C, respectively. Thermal conductivity of the tube wall is 385 W/mK. 1a. Draw the thermal resistance circuit of the system 1b. Derive the energy balance of the system 1c. Calculate the heat transfer coefficients inside the tube 1d. Calculate the heat loss occurring along the tube Water Internal diameter 50 mm Wall thickness = 5 mm Length = 50 cm
