We can find the change in the enthalpy through the tables A5 for Saturated water, pressure table.
For 1bar=1000kPa:
Replacing,
With the specific volume we know can calculate the mass flow, that is
Then the heat required in input is,
With the same value required of 15000m^3/h, we can calculate the velocity of the water, that is given by,
Finally we can apply the steady flow energy equation, that is
Re-arrange for Q,
We can note that consider the Kinetic Energy will decrease the heat input.
Forces exerted by the jet on the plate is=3976N
<h3>How to calculate forces exerted by the jet on the plate?</h3>A force is an effect that can change the motion of an object. A force can generate an object with mass to change its velocity, i.e., to accelerate. Force can also be explained intuitively as a push or a pull. A force has both volume and direction, making it a vector amount.
A jet of water 75m in diameter
velocity = 30m/s
The forces exerted by the jet on the plate is
F=1000×44178×10^-3×30²
=3976N
the jet on the plate work done by Is zero .
