Water at 80F is flowing from A to B in a 3-in coated ductile iron pipe. Point B is 20ft higher than A, and the total length of pipe is 60ft. Two 90 long radius, flanged elbows are installed between A and B. Calculate the volume flow rate of water if the pressure at A is 120 psi and the pressure at B is 105 psi. Use Darcy-Weisbach for this analysis.
