In the branched pipe system shown, 850 L/min of water at 10°C is flowing in a DN 100 Schedule 40 pipe at A. The flow splits into two DN 50 Schedule 40 pipes as shown and then rejoins at B. Calculate (a) the flow rate in each of the branches and (b) the pres- sure difference PA PB. Include the effect of the minor losses in the lower branch of the system. The total length of pipe in the lower branch is 60 m. The elbows are standard.

Design a rapid mix tank for water at 50° F flowing at Q = 4.0 MGD for a typical process train ina drinking water treatment plant. Use a square tank with a depth 1.25 times the width, a designvelocity gradient G = 900 sec−1, and a hydraulic detention time τ = 30 seconds. Specificallydetermine:a. Rapid mix tank dimensions in feet and inches, to the nearest one inch.b. Input water horsepower (hp).c. Impeller rotational speed if a vane-disc impeller is used having a diameter half of the tankwidth and employing six flat blades and a baffled tank.

A pipeline 200 meters long delivers water from an impounding reservoir to a service reservoir with the difference in water levels of 20 meters. The pipeline of commercial steel is 400 mm in diameter. It has two 90 degree flanged elbows, a check valve, and an orifice (K_m= 2.5). Determine the flow through the pipe. Use a water temperature of 20 degrees Celcius.
