Power of the motor is 70 KW.
That is 70000 Watt
That is 70000 joule /sec
That is 70000 N-m/s
Now we know that
Power =Force * velocity
That means if a pump has power X then it can raise a load of Y N with a speed of X/Y
Now we are given that X=70000
And Y=10
Hence The speed at which the load can be raised is
70000/10=7000m/s
That is 70000 Watt
That is 70000 joule /sec
That is 70000 N-m/s
Now we know that
Power =Force * velocity
That means if a pump has power X then it can raise a load of Y N with a speed of X/Y
Now we are given that X=70000
And Y=10
Hence The speed at which the load can be raised is
70000/10=7000m/s
