Water with density of p=1.94 slug/ft3 and dynamic viscosity of 2.34X10-5 slug/ft.s flows from the basement to the second floor through the 0.75 in (0.0625 ft)-diameter copper pipe (a drawn tubing wit e=0.000005 ft) at a rate of Q=12.0 gal/min=0.0267 ft3/s and exits through a faucet of diameter 0.50 in. as shown in the figure
K1 = 2 based on pipe velocity -10 ft- 10 ft (7)|(8) (2) (6) 0.75-in.-diameter copper pipe 5 ft 10 ft Wide open globe valve (4) 0.50-in. diameter (5) Q = 10 ft 8 12.0 gal/min (3) (1) Threaded 90° elbows -15 ft
Determine the pressure at point (1) if (a) all losses are neglected (b) the only losses included are major losses, or (c) all losses are included (Loss coefficients for minor loses: Kl=1.5 for each elbow, Ku=10 for wide open globe valve, and KL=2 for the faucet, and all based on the pipe velocity)
