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

Answer:

The mass flow rate of jet =69.44 kg/s

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

$P=mass\ flow\ rate\ \times v^2$

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
