- After graduation, you work for a pump manufacturing company. One of your company’s best-selling products is a water pump, which we shall call pump A. Its impeller diameter is DA = 6.0 cm, and its performance data when operating at n. A = 1725 rpm (?A = 180.6 rad/s) are shown in Table.The marketing research department is recommending that the company design a new product, namely, a larger pump (which we shall call pump B) that will be used to pump liquid refrigerant R-134a at room temperature. The pump is to be designed such that its best efficiency point occurs as close as possible to a volume flow rate of V. B = 2400 cm3 /s and at a net head of HB = 450 cm (of R-134a). The chief engineer (your boss) tells you to perform some preliminary analyses using pump scaling laws to determine if a geometrically scaled-up pump could be designed and built to meet the given requirements. (a) Plot the performance curves of pump A in both dimensional and dimensionless form, and identify the best…1.A vertical cylindrical tank has an orifice for its outlet. When the water surface in the tank is 5 m above the orifice, the surface can be lowered 4 m in 20 minutes, the pressure on the surface being atmospheric. What uniform air pressure must be applied to the surface if the same volume of water is to be discharged in 10 minutes?[Hydraulics] What is meant by the center of pressure? For a vertical surface immersed in a liquid, do you expect it to be located below or above the center of gravity and why
- What will be the diameter (in mm) of a waterjet, the pressure inside which is 0.00221 N/cm2 greater than the outside pressure? (Take surface tension as 0.075 N/m)What will be the diameter (in mm) of a waterjet, the pressure inside which is 0.00161 N/cm2 greater than the outside pressure? (Take surface tension as 0.075 N/m) Answer(20) Question 2 A hydraulic motor is directly coupled to the drum of a belt conveyor. The drum diameter is 0.75 m, the conveyor belt moves at a speed of 3 m/s and the motor must transfer a torque of 995 Nm to the drum. Assume the pressure drop across the motor is 22 MPa and that the motor has an overall and mechanical efficiency of 0.92 and 0.96 respectively. Determine the displacement volume of the motor, the flow rate required in litres per second and the hydraulic power supplied to the motor.
