13.liquid water at 294.26k flows in straight horizontal pipe in which there is no exchange of either heat or work with the surrounding its velocity is 9.144m/s in a pipe with an internal diameter of 2.54cm until it flows into a section where the pipe diameter abruptly increases .what is the enthalpy change of the water if the downstream diameter is 3.81 cm.if it is 7.62cm what is the maximum change in enthalpy for an enlargement in the pipe 13.liquid water at 294.26k flows in straight horizontal pipe in which there is no exchange of either heat or work with the surrounding its velocity is 9.144m/s in a pipe with an internal diameter of 2.54cm until it flows into a section where the pipe diameter abruptly increases .what is the enthalpy change of the water if the downstream diameter is 3.81 cm.if it is 7.62cm what is the maximum change in enthalpy for an enlargement in the pipe
