b) A steel pipe with heat transfer coefficient of
i. The heat loss by convection and conduction per meter length of un-insulated pipe when the water temperature is
Step 1 :Calculate the inner diameter of the pipe: D_inner = D_outer - 2 * t = 0.09 - 2 * 0.003 =
Step 2 :Calculate the area of the pipe's inner surface and outer surface per meter length: A_inner =
Step 3 :Calculate the heat loss by convection and conduction: Q =
Step 4 :
