A pump has a specific speed of 42 and 600 rpm when it delivers 0.01 m3/s. find the head developed by the pump. Answer:  1015.29 ft

10.0 m 200 m 2. An old western town has a water tower to deliver water to the residents. Pictured above is the water tower. The water tower is closed but there is a section of air that is atmospheric pressure just above the water. The corsss ectional area at point 2 is 4.75 x 10 m. The cross sectional area fot the water tower is very large. What is the speed of the water coming out of the pipe at point 2? (density of water = kg/m³) 3. On a vacation trip up in Oregon my boys decided to build a 10 kg raft that they made out of driftwood. 1000

A pumping station wet well operates between 540- and 550-ft elevation. The pump curve is deϐined by the following points: 80 ft at zero ϐlow, 78 ft at 200 gpm, 65 ft at 800 gpm, and 50 ft at 1200 gpm. The pump discharge contains an equivalent of 50 ft of 6-in. pipe. The discharge pipe is 120-ft long and terminates at a splitter box, elevation 570. Using C=100, plot the pump curve and the corrected pump curve. Plot the pump discharge curves at each wet well elevation and for C=100 and C=140. What is the pump ϐlow at the low and high wet well elevations for newand old pipe?

plz help

A turbine is installed as shown in the figure. The gage at point 1 is 80 kPa while at point 2 is -46 kPa. If the rate of flow is 0.48 cu.m. per second, compute the output horsepower if the efficiency of the turbine is at 82%. Pls answer as soon as possible
