Water is flowing in a straight horizontal pipe of 2.5 cm ID with a velocity of 6.0m/s. The water flows steadily into a section where the diameter is suddenly increased. There is no device present for adding or removing energy as work.

Help me sketch this, the solution is given below. Then answer this, How will these changes affect the temperature of the water?

Calculate the downstream velocity. 4 u = 4 = D 41 D (2.5) (6 m/s) (5)* =1.5 m/s Calculate the change in enthalpy of water. AH =? (x - 4) = }((6 m/s)?- (1.5 m/s)") = 16.87 J/kg Calculate the maximum enthalpy change. 1 u (6 m/s) 2 =18 J/kg AH
