Answer:
So the exit velocity of water is 4.5 m/s
Explanation:
Given that
Water entering pressure = 1.5 MPa
Temperature = 150°C
Velocity = 4.5 m/s
From first law of thermodynamics for open system
Here given that valve is adiabatic so Q= 0
In valve W= 0
Wen also also know that throttling process is an constant enthaply process so
So from above equation we can say that
So the exit velocity of water is 4.5 m/s
