A pump forces 1 m3/min of water horizontally from an open well to a closed tank where the pressure is 0.9 MPa. If the work done upon the water had been used solely to raise the same amount of water vertically against gravity without change of pressure, how many meters would the water have been elevated? What velocity would the water have reached in m/s? If the work had been used to accelerate the water from anitial velocity of 10 m/s, what would the final velocity have been in m/s?   Ans. (91.74 m ; 42.4 m/s; 43.6 m/s)

Question

 A pump forces 1 m3/min of water horizontally from an open well to a closed tank where the pressure is 0.9 MPa.

If the work done upon the water had been used solely to raise the same amount of water vertically against gravity without change of pressure, how many meters would the water have been elevated?

What velocity would the water have reached in m/s? If the work had been used to accelerate the water from anitial velocity of 10 m/s, what would the final velocity have been in m/s?

 

Ans. (91.74 m ; 42.4 m/s; 43.6 m/s)
