So here in this question, first we calculate the velocity of water jet at the inlet.
00:06
So velocity of water jet, water jet at inlet, that is v1 is equal to a square root of 2 g h, where g's acceleration due to gravity net is the cross head.
00:25
So v1 is equals to square root of 2 into 9 .8 meter per second square, fire into 400 and that is 89 .44 meter per second.
00:38
Then we calculate the velocity of the buckets, that is bb.
00:43
This is given as 0 .45 times the jet velocity, that is 0 .45 into 89 .44 and that is equals to 40 .25 meter per second.
00:55
Then we calculate the velocity of the buckets.
00:58
So we calculate the relative velocity of the water at the outlet.
01:03
So relative velocity is 85 % of the jet velocity, that is 0 .85 into 89 .44, and that is 75 .92 meter per second.
01:16
Then we calculate the power given to the runner.
01:19
So power is given by 0 .5 into row into v1 cube...
