2. At an average temperature of 100C, hot air flows through a 2.5 m long tube with an inside diameter of 50 mm. The temperature of the tube is C along its entire length. Convective film coefficient is 20.1 W/m2-K. Determine the connective heat transfer from air to the tube. a. 900 W. c. 624 W. b. 909 W. d. 632 W. Solution Q. h AT. Where: AGet Price
Should the system be powered by electricity (an immersion heater) then you need to check that your power supply is functioning. It might also be the case that the Residual Current Device (RCD) has been tripped by another circuit in the house. Any hot water cylinder powered by a gas boiler relies on the boiler to warm the water up.Get Price
