on the island, hydropower is expected to be extracted from a river of the river system via a pipe, 74 m long, to a turbine.During the dry season, from February to May the average daily flow rate of the river is 35 m3s-1 and for the remaining 8 months, the average daily flow rate of the water is 115 m3s-1. Assume, the initial capacity expenditure evaluated on a yearly basis of the run of a river system is $900 000, the annual operating cost is $17 500; and the density of water is 1000 kg ∙m-3.Considering the run of the river system above, determine(i) the energy potential at the source for one year,(ii) the levelized cost of electricity, and(iii) compare the LCOE value and the cost of electricity, and comment on the capital investment.

A centrifugal pump(efficiency 86%) lifts water through a total height of 42m from reservoir to discharge. Pumping is through 300m of 75mm diameter pipe at the rate of 20li/s. If pipe friction factor, f = 0.025, what KW is required? Answer: 9
In a liquor-bottling plant erected at a site 1 km above sea level (Patm=0.898 bar and temperature 8.7°C) where a centrifugal pump discharges 20 l/s of water against a head of 28 m while the cavita on parameter of the pump a=0.5. Where should the pump inlet location be in m with respect to the water surface.
Water at 16,2°C is to be discharged from a reservoir at a rate of 16,2 L/s using two horizontal cast iron (roughness value ɛ=0.00026m) pipes connected in series and a pump between them. The first pipe is 26,2 m long and has a 66,2 mm diameter, while the second pipe is 36,2 m long and has a 46,2 mm diameter. The water level in the reservoir is 30 m above the centerline of the pipe. The pipe entrance is sharp-edged (KL=0.562), and losses associated with the connection of the pump are negligible. Neglecting the effect of the kinetic energy correction factor, determine the required pumping head, the minimum pumping power and electric motor power for total efficiency value of 76,2% to maintain the indicated flow rate. Water density is r=996,2 kg/m3, dynamic viscosity µ= 1.162x10-3kg/ms. Solve the problem by making the necessary assumptions and drawing the schematic figure.
Explain why some pump performance curves may lead tounstable operating conditions.
Data: Hp2,3 = 2 m; A3 = 20 cm²; A₂ = 1 cm²; Hp0,1 = 0.8 m; NB= 74%(pump efficiency) To determine: a) the flow (L/s); b) the area of section (1) (cm³); c) the power supplied by the pump to the fluid.
A centrifugal pump pumps water at a flow rate of 7 m³/s to a height of 10 m. If the pump works at the best efficiency point, find the pump impeller diameter, pump speed, the best efficiency value of the pump, the head at the best efficiency value, and the specific speed of the pump, given that CQ=0.15 CH=6 CP=0.75.
1Two water pumps are arranged in series. The performance data for both pumps follow the parabolic curve fit Havailable =H0 =aV ^2. For pump 1, H0 =5.30 m and coefficient a =0.0438 m/Lpm^2; for pump 2, H0 =8.70 m and coefficient a =0.0347 m/Lpm^2. In either case, the units ofnet pump head H are m, and the units of capacity V are Lpm.Calculate the combined shutoff head. Complete Answer, thank you
In Fig. is shown a plot of pump net head as a function of pump volume flow rate, or capacity. On the figure, label the shutoff head, the free delivery, the pump performance curve, the system curve, and the operating point.
In the pump performance curve, the point at which the net head is zero is called (a) Best efficiency point (b) Free delivery (c) Shutoff head (d) Operating point (e) Duty point
A hydroelectric power plant site where the average elevation of the headwater is 565 m, the tailwater elevation is 485 m. The base of the centerline of the turbine nozzle is 10 m above the tailrace and the water flow was determined to be equal to that volume flowing through a rectangular channel 9 m wide and a depth of 1.20 m and an average velocity of 4.6 m/s. If the turbine efficiency is 95%, penstock efficiency is 90%, generator efficiency is 85%. The plant is operated 24 hours a day with a load factor of 0.70 and the utilization factor of 0.75. If the turbine is an impulse turbine, determine; The power output of the turbine. The average annual energy production.
