Hello everyone.
00:01
So according to a given numerical, we are talking about that is an engine okay and this is the engine pump, okay? the engine pump can be used and can be transferred some water.
00:14
The density is the water density.
00:18
This is the water density.
00:22
And the second thing is throws a passing from a hose pipe.
00:26
Water leaves the hose pipe, the cross -section area.
00:29
So cross -section area where the water will be passing.
00:34
So cross -section area is given cross -section area is given that is a a.
00:41
And when the water will be ejected out so that velocity of a ejection is given a v.
00:47
So first of all we calculate a rate at which kinetic energy imparted.
00:52
So first of all, v, kinetic energy.
00:54
So d differentiation of a kinetic energy and divided by time period...
