Fluid Mechanics: Fundamentals and Applications
- Water is to be withdrawn from a 7-m-high water reservoir by drilling a well-rounded 5-cm-diameter hole with negligible loss near the bottom and attaching a horizontal 90° bend of negligible length. Taking the kinetic energy correction factor to be 1.05, determine the flow rate of water through the bend if (a) the bend is a flanged smooth bend and (b) the bend is a miter bend without vanes.arrow_forwardWater at 20° C is siphoned from a reservoir as shown. For d = 8 cm and D = 16 cm, determine (a) the minimum flow rate that can be achieved without cavitation occurring in the piping system and (b) the maximum elevation of the highest point of the piping system to avoid cavitation. (c) Also, discuss the ways of increasing the maximum elevation of the highest point of the piping system to avoid cavitation.arrow_forwardWater 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.arrow_forward

Determine The Weight Flowrate, needed from the inflow pipe if the water depth remains constant, 0 — d=010marrow_forwardAt the bottom of a pressurized water tank is a mouth with a diameter of 5 cm, where water is discharged into the atmosphere. The water level is 2 m above the outlet. The tank air pressure above the water level is 300 kPa (absolute) and the atmospheric pressure is 100 KPA. Determine the initial rate of water discharge (volumetric flow rate) from the tank, neglecting the effects of friction.arrow_forwardWater flows through a venturi meter whose inlet diameter is 31 cm and throat diameter is 19 cm. The pressure at the inlet is 755kPa and at the throat 550 kPa. Determine the discharge in cumecs. Neglect head loss.arrow_forward
- A U-tube acts like a water siphon. The elbow in the tube is 1 m above the water surface, the tube outlet is L from point A below. When the length L is 5 m, the water emerges from the bottom of the siphon as free jet at atmospheric pressure. Determine the speed of the free jet and the minimum absolute pressure of the water at the elbow. (Patm= 101325 Pa, dsu=1000 kg/m3)arrow_forwardA hydroelectric power generating system is shown in the figure. Water flows from an upper reservoir to a lower one passing through a turbine at the rate of 286 liters per second. The total length of pipe connecting the two reservoirs is 186 m. The pipe diameter is 346 mm and the Hazen-Williams coefficient is 129. The water surface elevations of reservoirs 1 and 2 are 194 m and 69 m, respectively. Determine the power in kW required by the turbine if it is 63% efficient? Neglect minor losses. Round your answer to 3 decimal places.arrow_forwardA 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.arrow_forward
- 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.arrow_forwardTwo pipes, one circular and one square have the same cross-sectional area. Which has the larger hydraulic radius ? Show your solution to prove your answerarrow_forwardTwo water reservoirs A and B are connected to each other through a 40-m-long, 2-cm-diameter cast iron pipe with a sharp-edged entrance. The pipe also involves a swing check valve and a fully open gate valve. The water level in both reservoirs is the same, but reservoir A is pressurized by compressed air while reservoir B is open to the atmosphere at 95 kPa. If the initial flow rate through the pipe is 1.5 L/s, determine the absolute air pressure on top of reservoir A. Take the water temperature to be 10°C.arrow_forward
