Consider the following data relating to performance of a centrifugal pump: speed = 1200 rpm, flow rate = 30 l/s, head = 20 m, and power = 5 kW. If the speed of the pump is increased to 1500 rpm, assuming the efficiency is unaltered, the new flow rate and head, respectively, will be 46.9 l/s and 25.0 m 37.5 l/s and 25.0 m 46.9 l/s and 31.3 37.5 l/s and 31.3 m
A turbine system is harnessing the energy of flowing water from reservoir 1 to reservoir 2. The difference in elevation between the two reservoirs is 120ft. For a design flowrate of 50ft^3/s, the head loss is 30ft. Solve the theoretical power extracted by the turbine. Neglect the difference in atmospheric pressure between the reservoirs.

The Figure below gives an example of a network to pump water from a lower reservoir to an upper one. Widely used in buildings, industries and others. It is estimated that a building with 55 apartments of 3 bedrooms each. Consider 2 people. per room. The supply water is pumped from the lower reservoir to the upper one by means of lifting sets. Dimension the discharge and suction line, and the power of the motor-pump set; assuming a probable daily consumption of 2001 per inhabitant, Also consider that the day of greatest consumption is 25% more than normal consumption. The pumps will be capable of repressing the volume consumed daily, in just 6 hours of operation. Assume that the pipe diameter is D=1.3x/* Vē, where X = * and t is the number of hours the pump has been running. 2,0 m curve retention valve record 2,0 m bomb curve h=0 foot valve 2,5 m w o'os

A dam supplies to a suburban area using a 0.21m diameter pipeline that is 800m long. For the water to reach the intended reservoir, a pump is needed to raise the flow to a point 125m above the pump. If the flow within the pipe is 0.11 m3/s, determine the savings in horsepower if the engineers decided to replace the old pipe (f = 0.034 with a new 0.29m diameter pipe with f = 0.024.
