Question

y diagram to obtain the friction factors for this problem. Given a 6-inch pipe (e-0,0001 ft) carrying water. a. When the flow rate (Q) is 100 gpm. The Darcy-Weisbach friction factor, f b. When Q-900 gpm, f c. When Q: 1,500 gpm, f= 200-ft of water is equivalent to a pressure of psi. Think about the pressure at the base of a water tank where 2. the water level inside the tank is 200-ft above the base. Given 2,700-ft of horizontal 8-inch CIP carrying 950 gpm. a. Ne 3. The head loss due to friction over the length of pipe is f. If the pressure at the upstream end is 70 psi, the pressure at the downstream end is_psi. b.

Explanation / Answer

2). 1ft of water is equal to 0.433 psi therefore 200ft means 200*0.433= 86.7055

if you are measuring relative to vaccum and want to resolve the pressure relative to the atmosphere, then it should be like below...

1ft of water is -14.262 so 200ft =72 psi (pound/ square inch)

1). f=64/Re (reynolds number)

Re= VD/kv (kinematic viscosity)

a. 0.008

b. 0.065

c. 0.05
