Physics 34.1 Bernoulli's Equation & Flow in Pipes (14 of 38) Work=? to Pump Fluid: Ex.

In this video I will calculate the work-required=? needed to move 100m of water through a pipe where f=0.1, L=100m, v=0.5m, D=30cm a distance=d=100m.

Wow, amazing videos!! Helping thousands out there no doubt! Just fyi, I think the L value (100 m) is missing from the top part of the equation (after area). Thanks again, much appreciated.

So if there was no friction then the work done to pump 100 meters of fluid would be zero?

if we devide the work by the volume we get the pressure
i calculated that and i found it 0.04 bar
is that correct?
it is a smalle pressure
