5 Two reservoirs are connected by a pipeline, The diameter of the pipe is (0.5 m and the difference in levels of the two reservoirs is 12.5 m. The total length of the pipe is 1000 m. The velocity of flow in the pipe taking into account both major and minor losses will be [Take, friction factor f-0.04 and g 10 m/sec] (a) 1.75 m/s (c) 4.5 m/s (b) 3.2 m/s (d) 0.5 m/s
Reservoirs A and B with water levels at 72 m and 57 m respectively above datum are connected to a junction J located at 43 m above datum. A third pipeline connects a third reservoir with the junction. The pipeline parameters are as follows. Pipe reach Diameter (mm) 400 Length (m) The friction factor for all the pipes may be assumed as f = 0.02. If a pressure gauge at the junction reads 90 kN/m², determine the distribution of discharges in the three pipes and also the water surface elevation in the reservoir C. Neglect local losses.

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.

1] A pump draws water from an open reservoir, with a static suction headof 26.24 feet, and lifts it to another open reservoir with a static discharge head of25 meters. The diameter of the suction pipe is 15.24 cm and the diameter ofdischarge pipe is 4.0 inches. The total head loss from A to B is 25 % of the totaldynamic head (TDH), and the head loss at the discharge side of the pump is 90 %of the total head loss. The pump capacity is 50 lps. Determine: a) the pump brakepower if the efficiency is 82 %; b) the reading of the pressure gauge installed atthe suction side of the pump; and c) the reading of the pressure gauge installed atthe discharge side of the pump.
Reservoirs A and D are connected by a pipeline system as shown below. The water surface elevations at Reservoirs A and D are 100 ft and 80 ft, respectively. What is flow rate for each of the three pipes between B and C? The minor head loss coefficients are 0.5 and 1.0 for the entrance and the exit, respectively.
