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.

From the figure below, water must be pumped from the large tank below to the nozzle with an exit velocity of 5.8 m/s. The initial pump (Pump #1) that supplies 1.2hp of power to the water is not enough to produce the desired velocity. It is proposed that an additional pump (Pump#2) be installed as indicated to attain the desired value. Given the head loss for this flow is HL = 250Q^2, when Q is in m^3/s, determine the rated power (in hp) of Pump #2 if the mechanical efficiency of its motor is 86%.

Water is pumped from a supply reservoir to a ductile- iron water-transmission line, as shown in Figure 2.26. The high point of the transmission line is at point A, 1 km downstream of the supply reservoir, and the low point of the transmission line is at point B, 1 km downstream of A. If the flow rate through the pipeline is 1 m3/s, the diameter of the pipe is 750 mm, and the pressure at A is to be 350 kPa, then: (a) estimate the head that must be added by the pump; (b) estimate the power supplied by the pump; and (c) calculate the water pressure at B.

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.
