A 4-in schedule 40 pipe carrying water at 70 deg F splits into a 3.5 in schedule 40 bypass pipe that is 1250 ft long and a 3-in schedule 40 mainline that is 750 ft long. The two pipes join downstream in another 4 in schedule 40 pipe. The pressure drop over the bypass section is deltaP= 15psi What is the velocity in the bypass and the main pipe? What is the total volumetric flow rate in gallons per minute? Assume that the friction factor in both lines is f=.004.
