Problem 82HP
Pumps, Pipe and Channel Flows
A cutting tool uses a nozzle that generates a highspeed jet of liquidwater. Assume an exit velocity of 500 m/s of 20°C liquid water with a jet diameter of 2 mm (0.002 m). What is the mass flow rate? What size (power) pump is needed to generate this from a steady supply of 20°C liquid water at 200 kPa?

Problem 82HP
Pumps, Pipe and Channel Flows
A cutting tool uses a nozzle that generates a highspeed jet of liquidwater. Assume an exit velocity of 500 m/s of 20°C liquid water with a jet diameter of 2 mm (0.002 m). What is the mass flow rate? What size (power) pump is needed to generate this from a steady supply of 20°C liquid water at 200 kPa?
ANSWER:
Solution
Step 1 of 4
In this problem, we have to find the flow rate mass and also the power required to generate the steady supply.
