Find the diamter of a pipe where (p1-p2) is 55 psi and the height rise along the pipe is 60 ft or (h2-h1) = 60 ft (the exit is higher than the entrance ). there is a pump in a line with a head of 300 ft. the pipe is smooth. lenghth is 1500ft. Q=350 gal/min. the fluid is water, kinematic viscosity = 1*10^(-5) ft^2/sec.
