Water flows between two reservoirs through 800 ft of 12-inch diameter welded-steel pipe. The water surface elevation difference between the two reservoirs is 16 ft. Find the flowrate (a) assuming head loss is only due to pipe friction, and (b) Accounting for both friction losses and minor losses due to a flush square-edged pipe entrance, the pipe exit, and a half-open gate valve in the line. Assume the water temperature is 60°F

A pipe system connects two reservoirs whose difference in elevation is 150 ft. The pipe system consists of 1000 ft of 24 inch concrete pipe, branching into 1000 ft of 12 inch concrete pipe and 1200 ft of 18 ich concrete pipe in parallel, which join again to a single 24 inch line 2000 ft long. What would be the flow discharge in each pipe? assume f=0.02 for all pipes and assume that the minor losses can be neglected.

Two interconnected reservoirs have surface areas of 3000 and 1000m^2, respectively. The connecting pipe has a diameter of 0.3m, a length of 10,000m and a Darcy Weisbach coefficient f= 0.025. The initial difference in water surface elevation between the two reservoirs was 120m. Determine the time required for the difference to drop (1)110m, (2) 100m, and (3) 90m. Ignore minor losses.

Design a cast iron (kd=8*10‐4 ft) pressurized system (pipe diameter) that would convey water at 2 ft3/s from two elevated tanks separated 200 ft long. The difference in water surface elevation between the tanks is 20 ft and the kinematic viscosity is 1.217*10‐5 ft2/s. Along the system the entrance loss and the exit loss have a KL of 0.5 and 1, respectively. Two 90 degrees bends are present (KL=3) and a global valve (KL=10) is also installed along the system.

Water at 100oF flows from one tank to another through two pipes A (D=3") & B (D=6") running in parallel between the same two tanks through the same drop in elevation (25 ft). The lengths of the 3” and 6” new, asphalt-dipped cast iron pipe (ϵ = 0.0004 ft) are 100 ft. Use ν=7.4 x 10-6 ft2/s. Determine the flow in cfs . Ignoring minor losses ...determine QA and QB.
