sir, the formula clearly says that h=(P1-P2)/d.g according to derivation but you have taken (h- 20) to solve the problem. so the answers will be different. which one will be correct and why?
Sir, if we consider Uavg=-(dp/dx)*{(R*R)/(8*mu)}, I am getting different value!!, so according to the way problem solved in video we have to also consider the effect of gravity head, and why should we consider gravity loss to calculate Uavg???
Did he reply? I have got the same doubt. because the formula clearly says that h=(P1-P2)/d.g according to derivation but he is taking (h-20) to solve the problem.

One of the best sir.....he explain basics in a very simple way.
Thankyou sir , for resolve my most doubts.

EXCELLENT!!!

Why u not taken value of p1 and p2 directly from question
