Blowtorch is used to connect the two pipes together. Length of the pipe section shown is 95 cm with an inner diameter of 65 cm. The thickness of the pipe wall is 2.5 mm. The conductivity of the pipe section is 157 W/m^2K. Environment has a temperature of 20 C and convective heat transfer coefficient of 25 W/(mC) , find the required heat transfer to join the pipe sections at 220 C? HINT: Assume that the welding section is the base plate and the pipe is 1D extended surface (fin) symmetric about the torch melting line. Heat transfer happens by conduction along the pipe thickness in horizontal direction and by convection to the environment.
