Ariver flows down towards a lake along an incline. initially the river is 90 m above the lake flowing at a rate of 3 m/s. at the lake the velocity is 0 m/s. you are interested in the change of total energy per unit mass of the water. draw a schematic of the system, clearly identifying the system, and determine the change of total energy per unit mass of the water between the inlet and outlet of the system. assume that the internal energy of the water remains constant and that the pressure at the inlet and outlet is the same.
