A large number of 3.8-cm-OD pipes carrying hot and cold liquids are embedded in concrete in an equilateral staggered arrangement with centerlines 11.2 cm apart as shown in the sketch. If the pipes in rows A and C are at 16ºC while the pipes in rows B and D are at 66ºC, determine the rate of heat transfer per meter length from pipe X in row B.
