Mechanical energy balance equation
Our general mechanical energy equation, letting v = v a v g and α = 1, is ( P ρ + 1 2 v 2 + g z) 2 − ( P ρ + 1 2 v 2 + g z) 1 = w s − w f Considering our specific system, this general equation reduces to P 2 = P 1 − ρ w f Because w s > 0 and P 2 < P 1, it is clear that the frictional work has lead to a pressure loss/drop in our pipe.
