An orifice with a 1.8-in-diameter opening is used to measure the mass flow rate of water at 60°F (ρ = 62.36 lbm/ft³ and μ = 7.536 × 10^–4 lbm/ft·s) through a horizontal 4-in-diameter pipe. A mercury manometer is used to measure the pressure difference across the orifice. If the differential height of the manometer is 7 in, determine the volume flow rate of water through the pipe, the average velocity, and the head loss caused by the orifice meter.
