Water is stored in a large, well-insulated storage tank at 21.0°C open to atmosphere. It is pumped at a rate of 40 m3/h to another tank 25 m above, which is also open to atmosphere. The motor driving the pump supplies energy at the rate of 9.5 kW. The water passes through a heat exchanger where 255 kW of heat is added to the water. The total friction loss (ΣF) in the system is 90.25 J/kg. Determine the final temperature of the water at the second tank.

Applied Fluid Mechanics

A fluid is a substance that is continuously deformed by the application of shear stress. The rate of deformation of a fluid depends on its viscosity. The fluid tries to flow when it interacts with some other system.
