Problem 1An inventor claims that at steady state the device shown in the figure below develops power from entering and exiting streams of water at a rate of 1638 kW.

The accompanying table provides data for inlet 1 and 2 and exit 4. The pressure at exit 3 is 3 bar. Stray heat transfer and kinetic and potential energy effects are negligible. Evaluate the inventor's claim.(Hint: Write the first law first to find the unknown quantities)
