Example -5.2- It is required to pump cooling water from storage pond to a condenser in a process plant situated 10 m above the level of the pond. 200 m of 74.2 mm i.d. pipe is available and the pump has the characteristics given below. The head loss in the condenser is equivalent to 16 velocity heads based on the flow in the 74.2 mm pipe. If the friction factor = 0.003, estimate the rate of flow and the power to be supplied to the pump assuming n = 0.5 Q (m³/s) 0.0028 0.0039 0.005 0.0056 0.0059 Ah (m) 23.2 21.3 18.9 15.2 11.0
As shown in the picture blew, a pump can deliver volume flow rate of of water through a vertical lift of . The inlet to the pump is just below the water surface and the discharge is to the atmosphere through a DN50 schedule 40 steel pipe. The energy loss . (2) Select the correct simplified general energy equation for point 1 and 2
A "spa tub" is to be designed to replace bath tubs in reno- vations. There are to be 6 outlet nozzles, each with a di- ameter of 12 mm, and each should have an outlet velocity of 12 m/s. What is the required flow rate from the single pump that supplies all of these nozzles? If there is one suction line leading to the pump, what is the minimum diameter to limit the velocity at the inlet of the pump to 2.5 m/s?
Answer IT ASAP PLEASE.!! a 20 mm diameter steel pipe is used to drain and oil tank (SG-0.88) as shown. The total head loss is 2.904m, find the diameter of a new pipe that can replace the existing one such that the discharge is doubled Control Volume and the velocity of flow is maintained.
Calculate the power supplied to the pump shown if its efficiency is 75%. Water is at 25 degrees Celsius is flowing at the rate of 50.0 m3/h. The suction linf is a standard DN 100 Schedule 40 steel pip, 15m long. The total length of DN 50 Schedule 40 steel pipe in the discharge line is 200m. The elbows are tight, the entrance to the pipe is flush and the globe valve is completely open. Draw the line of total and piezometric heights.

4- A centrifugal pump was tested for cavitation initiation. Total head was 40 m and flow rate were 0.06 m/s. Cavitation started when the total head at the suction side was 3 m. The atmospheric pressure was 760 mm Hg and the vapor pressure at this temperature was 2 kPa. It was proposed to install the pump where the atmospheric pressure is 700 mm Hg and the vapor pressure at the location temperature is 1 kPa. If the pump develops the same total head and flow, can the pump be fixed as the same height as the lab setup? What should be the new height.
In Figure below, the pipe entrance is sharp-edged having K1 = 0.5, and for the open globe valve assume K2 = 6.0.
