Water at 15°C is to be discharged from a reservoir at a rate of 18 L/s using two horizontal cast iron pipes connected in series and a pump between them. The first pipe is X= 5 m long and has a 6-cm diameter, while the second pipe is 5 m long and has a 4-cm diameter. The water level in the reservoir is 30 m above the centerline of the pipe. The pipe entrance is sharp-edged, 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 and the minimum pumping power to maintain the indicated flow rate. (The density and dynamic viscosity of water at 15°C are ρ = 999.1 kg/m3 and μ = 1.138x10-3 kg/m.s. The loss coefficient is KL = 0.5 for a sharp-edged entrance. The roughness of cast iron pipes is ε= 0.00026 m.)

1. Water flows through a venturi meter. At the constricted section where the area is 24cm², the pressure is 10.2N/cm², and at the section where the area is 64cm², the pressure is 18.0N/cm². Determine the velocities of water in the larger and smaller pipes and the rate of flow. 2. Why is a water tower generally placed on top of a hill? If the hill is 50m high, can it supply water to the top of a 100-m tal officebbuilding? If not, how does water get to that floor?.
Water at 5°C is drained from a large reservoir using 2 horizontal copper pipes connected in series as shown in Figure 1.3. The first pipe is 20 m long with 0.2 cm diameter, while the second pipe is 35m long with 0.1 cm diameter. The water discharged from the pipe at 5 g/s.

A horizontal water pipe of diameter 15cm converges to7.5 cm diameter. If the pressure at the two sections are 400KPa and 150KPa respectively, calculate the flow rate of water.
Water at 10°C flows from a large reservoir to a smaller one through a 5-cm-diameter cast iron piping system, as shown in Fig. Determine the elevation z1 for a flow rate of 6 L/s.
In a hydroelectric power plant, water at 20°C is supplied to the turbine at a rate of 0.55 m3/s through a 200-m-long, 0.35-m-diameter cast iron pipe. The elevation difference between the free surface of the reservoir and the turbine discharge is 140 m, and the combined turbine–generator efficiency is 85 percent. Disregarding the minor losses because of the large length-to-diameter ratio, determine the electric power output of this plant.
Water at 15°C is drained from a large reservoir using two horizontal plastic pipes connected in series. The first pipe is 20 m long and has a 10-cm diameter, while the second pipe is 35 m long and has a 4-cm diameter. The water level in the reservoir is 18 m above the centerline of the pipe. The pipe entrance is sharp-edged, and the contraction between the two pipes is sudden. Neglecting the effect of the kinetic energy correction factor, determine the discharge rate of water from the reservoir.
