Question

A water jet that leaves a nozzle at 60 m/s at a certain flow rate generating power of 250 kW by striking the buckets located on the perimeter of a wheel. Determine the mass flow rate of the jet.

Answer 1

The mass flow rate of jet =69.44 kg/s

Step-by-step explanation:

Given that

velocity of jet v= 60 m/s

Power P=250 KW

As we know that force offered by water F

`F=\rho\ A \ v^2`

Power P= F.v

So now power given as

`P=\rho\ A \ v^3`

We know that mass flow rate = ρAv

`P=mass\ flow\ rate\ * v^2`

250 x 1000 = mass flow rate x 3600

mass flow rate = 69.44 kg/s

So the mass flow rate of jet =69.44 kg/s
