Liquid ammonia flows through a 2.5 cm inside diameter tube which is 2.5 m long. The ammonia flow rate is 0.5 kg/sec. The ammonia enters at 10 oC and leaves at 38 oC and a constant heat flux is imposed on the tube wall. If the flow is considered to be fully developed over the entire length of the tube, determine the tube wall temperature as a function of distance from the entrance.
