Extracted text: Heat Loss from a Buried Pipe. A water pipe whose wall temperature is 300 K has a diameter of 150 mm and a length of 10 m. It is buried horizontally in the ground at a depth of 0.40 m measured to the center line of the pipe. The ground surface temperature is 280 K and k = 0.85 W/m · K. Calculate the loss of heat from the pipe. Ans. q = 451.2 W
