Aheat exchanger contains 400 tubes with inner diameter of 23 mm and outer diameter of 25 mm. the length of each tube is 3.7 m. the corrected log mean temperature difference is 23°c, while the inner surface convection heat transfer coefficient is 3410 w/m2 ·k and the outer surface convection heat transfer coefficient is 6820 w/m2 ·k. if the thermal resistance of the tubes is negligible, determine the heat transfer rate.
