Solve each problem involving the applications of first law of thermodynamics. Write your complete solution on a separate sheet of paper. Use two decimal places for your final answers. Also, sketch the energy diagrams for each problem.

Tip : Research each fluid machineries used in each problems to understand better the flow of energy.

Fluid Machinery 1: Centrifugal Pump. It is used to transport a fluid from one point to another. Description: A centrifugal pump transports a 2.27 metric tons per minute of water under a steady flow condition. The initial pressure of the water is at 82.74 kPa then increased to 275.8 kPa. The diameter of the inlet pipe is 6 inches while the outlet pipe is 4 inches. Calculate the Horse Power. Note that the fluid used is water
