A Kaplan turbine has the following specifications: H =25 ft., N=400 rpm; power = 650 hp. If the efficiency of the unit is 90%, estimate (a) the flow rate, (b) approxi-mate diameter of the runner, (c) turbine setting to avoid cavitation if the location is at sea level, and (d) turbine setting to avoid cavitation if the location of the unitis at an elevation of 5000 ft. The local temperature is 60°F.Ans: (a) Q=254 cfs; (c) Hs=5.8 ft.; (d) 0.12 ft.
A certain centrifugal pump was tested and its performance curves can be approximated as follows: H = 340 - 1.2(Q2), in feet BP = (0.0521Q3) + (1.25Q2) + (11.042Q) + 134.5, in horsepower where Q is in ft3/s. If two of this pump is connected in series to deliver water to a system whose head requirement is 615 ft, what will be the operating discharge rate in ft3/s of either pumps?

Hello i have an example with an answer , please show the solution since only the answer was shown in this example. And i need its solution to review properly. Thank you 1.Question : An existing pump is used to pump water with the following data at BEP: D = 2.15 in, N = 1784 rpm, ρ = 998 kg/m3, Q = 18 gpm, H = 4.2 ft. A larger pump is to be designed based from the existing one to be used for pumping slurry (ρ = 1220 kg/m3) such that its best efficiency point occurs as close as possible to a volume flow rate of 48 gpm and at a net head of 15 ft. Calculate the new pump diameter in inches. Round off your final answer to 3 decimal placesAnswer: 2.554
You only know one point on a pump curve, where a water pump produces 20 m of hydraulic head at flow rate of 3.67 L/s, and you want to use this to pump water from a lower tank to an upper tank located 15 m higher. Both tanks are open to the atmosphere. Briefly explain your reasoning, in 1‐2 sentences, for each of the following. a) Should this pump be placed next to the lower tank or the higher one? b) Given the data point you have from the pump curve, will the flow rate be higher or lower than 3.67 L/s if the water is pumped exactly 15 m uphill?

The original design of a hydraulic turbine has data as follows: flow rate of 1 cumex, effective head of 50 m, and runner diameter of 1.5 m. If the same turbine design is to be used in another application where the available flow is 2.5 cumex and effective head is 75 m, what would be the runner diameter (in meters) for this new application?
