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
Explanation: For main group elements, the number of valence electrons is the same in every element in the same group. Group 1 elements have 1 valence electron in the s orbital.
