a
pump that delivers 4.5 kw to the water (v=0.898x10^-6 m^2/s ;
p=99.1kg/m^3) is used to fill a cylindrical tank as shown,
calculate the flow rate and the depth of the water in the
cylindrical tank 5 minutes after the pump is started. Assume the
sum of the loss coefficients of the fittings=12.8

1 A pump delivers water from the lower reservoir to the upper reservoir at a rate of 60 L/s. Both the suction and discharge pipes are DN 150 schedule 40steel pipe. The length of the suction pipe leading to the pump is 3.5 m, and 7 m of discharge pipe extend from the pump outlet to the upper tank. There are three standard 900 elbows and a fully open gate valve. The depth of the fluid level inside the lower...
1. A pump steadily delivers 13.7 kg/s of water at the conditions given below. Calculate the pump power (hp). There is no heat transfer from the pump to the surroundings (i.e., adiabatic conditions). Pump Inlet Temperature = 20oC Pump Inlet Pressure = 182 kPa Pump Inlet Diameter = 11.1 cm Pump Inlet Elevation = 20 m Pump Exit Temperature = 20oC Pump Exit Pressure = 601 kPa Pump Exit Diameter = 7.8 cm Pump Exit Elevation = 20 m Answer...
A centrifugal pump takes water from the bottom of a supply tank and delivers it into the bottom of another tank. The water level in the discharge tank is 50m above the level in the supply tank. The line between the tanks is 200m of 4-in commercial steel pipe. The ow rate is 1200 l/min. In the line, there two gate valves, four standard tees and four elbows. What is the energy cost of the running this pump for one...
Problem #1: A 4.5 kW pump operating at steady state draws in liquid water at 1 bar, 15 °C and delivers the water at 5 bar to a location whose elevation is 6 m above that of the inlet. There is no significant change in velocity between the inlet and exit, and the local acceleration of gravity is 9.8 m/s? Would it be possible to pump 5.5 m in 10 min or less? Explain. (25 pts)
Fig. Q4 shows a piping arrangement used in a food processing facility to transfer water, at 40 C, from a tank, through a heat exchanger to an elevated tank. A suitable pump is selected which, when installed, delivers the water at 2.5 m'/hr. The pipe diameter is 40 mm and the Absolute Roughness of the pipe material is 0.00008 m. The Loss Coefficients [K Factors] for the Bend and Heat Exchanger are shown in Fig. Q4 4. 2 m K...
QUESTION 5 A pump steadily delivers 17.2 kg/s of water at the conditions given below. Calculate the pump power (kW). There is no heat transfer from the pump to the surroundings (i.e., adiabatic conditions). Pump Inlet Temperature = 20°C Pump Inlet Pressure - 192 kPa Pump Inlet Diameter = 13.3 cm Pump Inlet Elevation = 22 m Pump Exit Temperature = 20°C Pump Exit Pressure - 419 kPa Pump Exit Diameter = 3.9 cm Pump Exit Elevation = 41.4 m...
A hydraulic pump delivers 0.5 m³/s of water against a head of 5.5 m. If the power needed to drive the pump is 33 KW, calculate the efficiency
If a pump with the characteristic curve shown in the accompanying graph (Figure 2) is used to pump water from the lower to the upper tank (water flows from Tank 2 to Tank 1 in this question) shown in Figure 1. Use information provided in Figure 1 and assume that diameter of pipe AB is 600 mm (DAB 600 ) and diameter of pipe BC is 300 mm DBc 300 mm) a. Find the operation point of this systenm b....
A 4-kW pump operating at steady state draws in liquid water at 100 kPa, 15?C with a mass flow rate of 4.5 kg/s and delivers water at 1 MPa pressure. Ignore the kinetic and potential energy changes from inlet to exit. Determine (a) the isentropic efficiency of the pump and (b) whether the power input rating is adequate
