For the question (check the image)
I need:

1. Give the assumption(s) required, the principle(s) to be applied to problem

2. What is the work in HP?

1. A 5lb / sec of fluid approaches a steady-state, steady flow system with
pressure input properties of 100psia, density=0.21b / cu.ft, speed= 100fps,
800Btu/ lb internal energy and pressure-20psia, density=0.05lb / cu.ft,
speed=500fps, and 780Btu/ lb internal energy. Each pound rejects 10 Btu of
heat during the passage through the open system.
