Textbook Question
Chapter 10, Problem 42P
Sometimes the variation of water viscosity with temperature can be used to achieve dynamic similarity. A model pump delivers 0.10 m3/s of water at 15°C against a head of 27 m, when operating at 3600 rpm. Determine the water temperature that must be used to obtain dynamically similar operation at 1800 rpm. Estimate the volume flow rate and head produced by the pump at the lower-speed test condition. Comment on the NPSH requirements for the two tests.

- Flow turbulence and cavitation in a centrifugal pump generate a similar sound to the human ear. Explain how vibration analysis would help you to determine which is which.arrow_forwardA centrifugal pump when tested with Brine of density 1190 kg per cubic meter discharged 60 liter per second against a pressure of 300 kPa. It is desired to investigate the change in power when a similar pump is used to pump petrol of density 700 kg per cubic meter against the same pressure. It is desired to keep the speed the same. Check whether any change in the drive motor is required. Assume an overall efficiency of 70% in both cases.arrow_forwardA centrifugal pump is driven by a motor. The performance of the pump reveals the folowing information: Power input to the pump by the motor (kW): 0.5, 0.7, 0.9, 1.0, 1.2 Power input to the fluid by the pump (kW): 0.3, 0.55, 0.7, 0.9, 1.0 Plot the efficiency curve. The efficiency of a pump is a function of the flow rate. Assume that the flow-readings corresponding to to power data points are equally spaced.arrow_forward
- 1. For a given pump, the diameter, the gauge pressures at the inlet and outlet are −30 × 103 P a and 200 × 103 P a, respectively. If the flow rate is 0.1 m3/s, and the power required is 25 kW, find the efficiency. The intake and discharge are at the same height. 2. The impeller of a radial-flow turbine has an outer radius of 4 f t, turning at 200 rpm. The volume flow rate is 1000 ft3/s, and it discharges in the axial direction. Neglect all losses. If the tangential component of the velocity at the inlet is 5 f t/s, find: (a) The torque exerted on the impeller. (b) The power developed by the machine.arrow_forwardA pump delivers 10 L/min with a pressure rise of 80 bar. The shaft speed is 1420 rev/min and the volumetric displacement is 8 cm3/rev. The theoretical torque is 11.4 Nm. Calculate the volumetric efficiency of the pump. (ii) If the power supply to the motor that drives the pump is now reduced by 50%, what would happen to the volumetric efficiency of the pump? Support your answer with relevant calculations. You may propose your own scientific assumptions.arrow_forwardExample: A fan of diameter 0.7 m running 1500 rpm delivers 140 m3/min of air at 15C against 75 mm of water total pressure when the total effeciency is 86%. Determine the volume of air delivered, total pressure and power consumed, if (a) the air temperature is 50C. (b) the air temperature is 50C and the fan speed is 1700 rpm. (c) the same conditions as (b) but a 0.6 m diameter, geometrically similar fan is used.arrow_forward
- Solve problem 2 (Textbook, p. 230). This is a case example how to use the characteristic curve of a pump to find the operation point of a piping installation. You can find the solution graphically, iteratively (if you want to fit the curve of Fig. P4.2 with an equation) or using trial and error (my recommendation). 2. Pump and pipeline—M . The head/discharge curve of a centrifugal pump is shown in Fig. P4.2. The exit of the pump is connected to 1,000 ft of nominal 2-in. diameter horizontal pipe (D = 2.067 in.). What flow rate (ft^3/s) of water can be expected? Assume atmospheric pressure at the pump inlet and pipe exit, and take fF = 0.00475.arrow_forwardA series of experiments were carried out to obtain the characteristics of a centrifugal pump at a given speed. In the experiments, the pump head (H) against different flow (Q) values were obtained as follows. Obtain a second-order polynomial equation for this centrifugal pump that gives the variation of head with flow.arrow_forwardThe cylinder bore diameter of a single-acting reciprocating pump is 150 mm and its stroke is 300 mm. The pump runs at 60 rpm and lifts water through a height of 30 m. The delivery pipe is 22 m long and 100 mm in diameter. Find the theoretical discharge and the theoretical power required to run the pump. If the actual discharge is 4.2 liters/s, find the percentage slip and determine the acceleration head at the beginning and middle of the delivery stroke.arrow_forward
