2.25. Water at 28°C flows in a straight horizontal pipe in which there is no exchange of al reither heat or work with the surroundings. Its velocity is 14 m s-1 in a pipe with an internal diameter of 2.5 cm until it flows into a section where the pipe diameter abruptly increases. What is the temperature change of the water if the downstream diameter is 3.8 cm? If it is 7.5 cm]? What is the maximum temperature change for an enlargement in the pipe?
