Low flow can cause overheating, hydraulic instabilities (suction and discharge recirculation) and mechanical unreliability in centrifugal pumps. To prevent such problems, options include both continuous and automatic (active) low-flow protection systems. Figure 1 shows four major types of configurations that provide recirculation back to an upstream feed vessel. Alternatives include recirculation to the pump suction piping.

What is purpose balance line in centrifugal compressor?
The purpose of the balance line in a centrifugal compressor is to equalize the pressure between the high-pressure and low-pressure sides of the impeller. This helps to reduce axial thrust, which can lead to mechanical wear and inefficiency. By allowing a controlled flow of gas or liquid to bypass the impeller, the balance line aids in stabilizing rotor operation and improving overall performance. It is essential for maintaining the reliability and longevity of the compressor system.
Is there a required minimum pipe size for a shower?
1/2" water lines. Drain line determined by flow rate of showerheads and bodysprays being used. 5.7 gpm or less flow rate would need 1 1/2" drain, which is minimum size allowed.
What is surge limit in cetrifugal compressor?
Surge Limit is the Minimum Flow Point ( in the compressor characteristic curve ) below which the compressor operation become instable. If the flow-rate is reduced, the pressure developed by the compressor decreases. Then, the pressure in the discharge line becomes greater , and the gas flow back into the compressor. As soon as the pressure in the discharge line drops to below that developed by the compressor, the gas again flows in the discharge line. Then, the cycle repeats. The oscillating pressure and flow rate will cause audible vibrations and shocks, and could damage the compressor blades, seals, and other components. Therefore, the compressor requires an antisurge control system to limit the flow rate at a minimum point, safely away from the surge limit.

When the neutral switch is open where do the line current flow to?
There is never a switch installed in a neutral line.

Why line reducer is used for centrifugal pumps?
cavitation formed wen concentric reducer in used. but wat is the use of reducer in the both suction and discharge side of the pump. if we dost use (conc & ecc) reducer in the both sides.. there is not effect on pump
What is the difference between axial in-line fans and centrifugal inline fans?
Axial fans are like a propeller - like most domestic fans. Centrifugal fans are like water or paddle wheeels that sit inside a case. Instead of water turning them, the wheel is driven by the motor and that moves the gas. In-line merely means that the fan sits in the gas flow.
What is the purpose of the water supply line valve in a toilet?
The purpose of the water supply line valve in a toilet is to control the flow of water into the toilet tank, allowing the user to fill and flush the toilet as needed.
Why centrifugal pump is not called a positive displacement type of pump?
A positive displacement pump causes a fluid to move by trapping a fixed amount of it then forcing (displacing) that trapped volume into the discharge pipe. Centrifugal pumps impart pressure to the fluid, to cause a pressure differential and cause flow, but even if the outlet is sealed, the pump can continue to run because it hasn't trapped the fluid. When no flow is occurring, a centrifugal pump acts like a propeller spinning in the water. If flow is stopped on a line that a positive displacement pump is supplying flow to, the pump is forced to stop since the trapped fluid prevents it from moving any more fluid.
What is the purpose of the refrigerator water line valve and how does it function within the refrigerator system?
The purpose of the refrigerator water line valve is to control the flow of water to the refrigerator's water and ice dispenser. It functions by opening and closing to allow water to flow into the refrigerator's water system when needed, and shutting off the flow when not in use to prevent leaks or flooding.
Is there a required minimum pipe size for a shower?
1/2" water lines. Drain line determined by flow rate of showerheads and bodysprays being used. 5.7 gpm or less flow rate would need 1 1/2" drain, which is minimum size allowed.
What is the purpose of a shut off valve for an ice maker water line and how does it function to control the flow of water to the ice maker?
The purpose of a shut off valve for an ice maker water line is to control the flow of water to the ice maker. It functions by allowing you to turn the valve on or off to either allow water to flow to the ice maker or stop the flow of water completely. This control helps in situations such as maintenance or repairs, as well as preventing leaks or flooding.
Why centrifugal force is zero when a particle moves along straight path?
The expression for centrifugal force is m v2 / r. For a straight line radius of curvature r is infinity. So the centrifugal force will become 0 as 1/infinity = 0
What best explain the significance of the continental divide?
It has no 'purpose' it is a natural occurring division. The continental divide is a line that runs down through the Rocky Mountains and on the west side of the line rivers and streams flow down toward the Pacific Ocean and on the east side of the line rivers and streams flow towards the Atlantic Ocean.
What is the purpose of a t valve in a water line system?
A T valve in a water line system is used to control the flow of water by diverting it in different directions. It allows for the regulation of water flow to different areas or appliances, providing flexibility and efficiency in the water distribution system.
