Shows a horizontal ring main, which consists of a continuous loop of pipe, such as might be used for supplying water to various points on one floor of a building. Water enters the main at A at 50 psig, and is discharged at B and C at rates of 20 gpm and 60 gpm, respectively. Tests on the particular pipe forming the main show that the frictional pressure drop (psi) is given by –Δp = 0.0002 Q2L, where L is the length of pipe in feet and Q is the flow rate in gpm. Estimate the flow rate in the section AC and the pressure at B. Was the flow during the tests laminar or turbulent?
