Concept explainers
A water pump is used to pump water from one large reservoir to another large reservoir that is at a higher elevation. The free surfaces of both reservoirs are exposed to atmospheric pressure, as sketched in Fig. P 14-39. The dimensions and minor loss coefficients are provided in the figure. The pump' s performance is approximated by the expression

- Flow takes place between three reservoirs, as shown in Figure 1. The volume flow rate out of reservoirs A and B is 0,15 m³/s and 0,25 m³/s respectively. If the coefficient of friction for three pipes is 0,008, determine the relative elevations of the free surfaces. Neglect all losses other than friction. May you kindly resend the answers in a different format as they appear blank??arrow_forwardThe water is flowing through a pipe having diameters 45 cm and 15 cm at sections 1and 2 respectively. The rate of flow through pipe is 35 litres/s. The section 1 is 6 m above datum and section 2 is 4 m above datum. If the pressure at section 1 is 36 N/cm2, find the following by neglecting losses: (ENTER ONLY THE VALUES BY REFERRING THE UNIT GIVEN IN BRACKETS) ) Area of cross section of section1 (unit in m?) = Area of cross section of section2 (unit in m?) = velocity at section 1 (unit in m/s) = velocity at section 2 (unit in m/s) =arrow_forwardQ2/ A fluid containing (water, oil, sand) flowing through the tube and open to the atmosphere as shown in the figure below..

- Fastarrow_forwardImagine that you are recently bought a 2-floor house and want to improve the water installation at the top floor which is 15 m from the water meter. Suppose that the water installation is poor due to 3 reasons: The city water pressure is not adequate (p = 200 kPa), the piping has a small diameter (D = 1.27 cm) and has been crudded up, increasing its roughness (e/D = 0.05). After a brief analysis you decide that there are 2 options to solve the problem: Either replacing the piping system with the smooth new pipe (D = 1.9 cm) or installing the boost pump (p = 300 kPa) while keeping the old piping system. By neglecting minor losses, which one would be more effective? (keeping in mind that combining these 2 options will surely solve the problem, but with more expenses)arrow_forwardThe figure below shows a turbine with an inlet pipe and a draft tube.

- A pump is installed to deliver water from a reservoir of surface elevation zero, to another of elevation 290 ft. The 10 inch-diameter suction pipe (f=0.022) is 90 ft long and the 8-in-diameer discharge pipe (f=0.028) is 4900 ft long. The pump characteristic is defined by hp= 365-20Q2 where hp, the pump head, is in feet and Q is in cubic feet per second. What is the rate at which the pump will deliver the water?arrow_forwardThree pipes are connected in series with properties given as: for pipe A, L= 300 m, diameter = 15 cm, for pipe B, L= 400 m, diameter= 20 cm and for pipe C, L= 600 m, diameter= 25 cm. The Manninbg's coefficient of the three pipes n= 0.011.
