Acentrifugal pump is required to pump water to an open water link situated 4 km away from the location of the pump through a pipe of diameter 0.2 m having darcy's friction factor of 0.01. the average speed of water in the pipe is 2 m/s. if it maintains a constant head of 5 m in the tank, what is the corresponding pressure in bar abs.

P= 5.5 bar

Explanation:

Given that

L= 4000 m

d= 0.2 m

Friction factor(F) = 0.01

speed V= 2 m/s

Head = 5 m

Head loss due to friction

So the total head(H) = 5 + 40.77 + 10.3 =56.07

Where 10.3 m is the atmospheric head.

We know that

P=ρ g H

So total Pressure

P= 1000 x 9.81 x 56.07 Pa

P= 5.5 bar

the army does care about its soilders sir i think yout getting off on the wrong foot sir you need to respect our country were keeping the peole that want to d harm towards you out. so dont go saying we don't care cause we do
