A reaction type hydro-electric plant use a 95% efficiency generator to produce its rated output of 20MW. It was observed during its operation that the mechanical loss is 2.5MW. Also from the penstock down to the turbine, 20% hydraulic head loss and 15% leakage loss occur which are equally distributed and based on the parameters at the dam. The average elevation from the headrace to the turbine is 30 m and from the tailrace to the turbine is 5 m. Compute the ff: a. Power by the turbine, kW b. Volume flow rate at the source, m3/s c.

A self-priming centrifugal pump is used to pump water at 25°C from a reservoir whose surface is 2.2 m below the centerline of the pump inlet. The pipe is PVC pipe with an ID of 26.0 mm and negligible average inner roughness height. The pipe length from the submerged pipe inlet to the pump inlet is 2.8 m. There are only two minor losses in the piping system from the pipe inlet to the pump inlet: a sharp-edged reentrant inlet (KL = 0.85), and a flanged smooth 90° regular elbow (KL = 0.3). The pump’s required net positive suction head is provided by the manufacturer as a curve fit: NPSHrequired = 2.2 m + [0.0013 m/(Lpm)2 ]V.2 , where volume flow rate is in Lpm. Estimate the maximum volume flow rate (in units of Lpm) that can be pumped without cavitation.
Determine the smallest metric hydraulic copper tube size that will carry 4L/min of thefollowing fluids while maintaining laminar flow: (a) water at 40°C, (b) gasoline(SG=0.68) 25°C, (c) ethyl alcohol (SG=0.79) at 0°C, and (d) heavy fuel oil at 25°C. answer correctly the last part only please thank you
2. A centrifugal pump installation has been designed to discharge 0.126 ?3/? of brine (sp.gr. = 1.2). The suction pipe is 305 mm and is at the same level as the discharge pipe which is 203 mm in diameter. At the centerline of suction flange, the vacuum is 154.2 mm Hg. The discharge pressure gauge reads 0.1379 MPa and is connected 1.22 m above the discharge flange centerline. The pump is driven by a 35 KW electric motor that will not carry overload and has an efficiency of 82%. There is no significant head loss. The design conditions have changed, and is now desired to increase the capacity of the pump by increasing the speed. The motor is so designed that its speed maybe increased but its power cannot exceed its design rating. Assuming the pump efficiency to remain constant, how much can the pump capacity be increased without overloading the motor?

The old Hydraulics laboratory in Mechanical Engineering used a roof tank tosupply apparatus with water at a nearly constant head. The water wascollected in an under floor sump, and then pumped back to the roof tankafter the experiment. The flow rate was 10 litre s-1. The tank was 6m abovethe sump, and the length of the pipe route was 15 m. The old 6” pipes arenow heavily corroded (k = 7.5 mm). The old pump has been scrapped. Whathead ΔH would be specified for a pump to restore the system using the oldpipes? What would the pump power be? If the pipes were replaced with 150mm diameter PVC pipes, what pump ΔH would be required?
The total length of pipe in the three inch branch is 20 ft, and the length of pipe in the one inch branch is 6 ft. Brine (sg=1.04, m=10-3 Pa*s) flows at 250gpm through the entrance at point A. Assume fully turbulent flow in both branches (f=ft). Pipes are standard Schedule 40 steel pipes. Assume the globe valve is partially shut so its equivalent L/D is 1000. determine The flow rate in both branches The pressure drop in both branches The overall resistance coefficient
1) Which of the following statement is NOT correct about piping network? a) In parallel pipes, the flow rate is proportional to its diameter and inversely proportional to its length and friction factor. b) When analyzing the piping network, conservation of mass throughout the system must be satisfied. c) In piping systems with pumps, the Bernoulli equation should be corrected by introducing a kinetic energy correction factor. d) The algebraic sum of head losses for all loops equal to zero. 2) The EGL is always a distance V2/2g above the HGL. True or False
