Water is pumped at a rate of 500 gpm through a 10 in. ID pipeline, 50 ft long, that contain two standard elbows and a swing check valve. The pressure is 1 atm entering and leaving the pipeline. Calculate the pressure drop (in psi) through the pipeline due to friction using (a) the 2-K method; (b) the ðL=DÞeq method; (c) the 3-K method.
