Water steadily flows from the basement to the second floor through a 0.75-in-diameter copper pipe. The volume flow rate is constant as Q = 12 gal/min (gpm). Water exits through a faucet having a diameter of 0.5 in. Consider all losses, and determine the pressure at (1) required to maintain the constant volume flow rate. If needed, use the tables below and the Moody chart on the last page. Water has a density of 1.94 slug/ft³ and a viscosity of 2.34 x 10-5 psf s, and the gravitational acceleration is = 9 32.2 ft/s². The following conversion relations can be used: 1 ft = 12 in, 1 gal = 0.160544 ft³. .

2. Water steadily flows from the basement to the second floor through a 0.75-in-diameter copper pipe. The volume flow rate is constant as Q = 12 gal/min (gpm). Water exits through a faucet having a diameter of 0.5 in. Consider all losses, and determine the pressure at (1) required to maintain the constant volume flow rate. If needed, use the tables below and the Moody chart on the last page. Water has a density of 1.94 slug/ft3 and a viscosity of 2.34 x 10-5 psf s, and the gravitational acceleration is g = 32.2 ft/s².
