- Please list any assumptions and answer all partsarrow_forward4. A pump is used for the pumping of water from Tank A into Tank B in which the height difference between the surface levels of water is 20 m. The pipe diameter is 400 mm and the pipe length is 2500 m, the coefficient of friction is f 0.0025 and the pump works at a speed of 700 rpm. The characteristics of the pump are shown in Table 4 below You are required to: (a) (10 points) Intepret pump characteristic and system characteristic ina graph. (b) (10 points) Calculate the input and output power at the operating point. 0.1 0.2 0.3 0.35 0.4 0.5 15 17 18 16 14 O30 60 SI83.80 45 H.

Plastic pipes used, with six bends and two gate valves, as shown. Given that the water is flowing at an average velocity of 2.5 m/s, calculate the required power input for the pump. Given: The density and viscosity of water at 60°C are p = 983.3 kg/m', u = 0.467x103 kg/m-s. Plastic pipes are smooth, and thus their roughness is very close to zero, ɛ = 0. The loss coefficient is K1 = 0.9 for a threaded 90° smooth bend and K1 = 0.2 for a fully open gate valve. Assume 70% pump efficiency. 1.2 cm Hot Water tank 40 marrow_forward
- A U tube differential manometer containing mercury was used to measure the difference of pressures in two pipes containing water. The difference in mercury level is 0.8 m, the level of water in left limb from mercury level to center of the left pipe is 1.9 m and the level of water in right limb from mercury level to center of the left pipe is 0.8 m. Find the head difference in m. S for water = 1, S for mercury 13.6. b. Draw a neat diagram shows all parameters. c. Discuss the differences between U tube and slanted U tube manometers.

- 11. AU-tube mercury differential manometer is used to measure the difference of pressure between inlet throat of a venturimeter placed with its axis horizontal in a pipeline. Calculate the difference in pressure between inlet and throat when the manometer reading is 250 mm and water flows through the pipeline. [Ans. 3.15 m of water]arrow_forwarda. Solve for the two (2) atmospheric condition, Pn1 & Pn2 at 32.68 0C and 41.12 °C. b. Calculate the diameter of the pipe at suction side if the velocity of air flow is 22.82 m/s with flow rate of 2.96 m³ /second. c.

It leaves the pump through a 4-inch diameter pipe at 15 psi. Assuming that the suction and discharge sides of the pump are at the same elevation, find the horsepower delivered to the water by the pump (550 lb.ft/s = 1 HP).
