What is theFunction of arc valve in boiler feed pumps?
The ARC valve provides protection for centrifugal pumps during low flow conditions. It recirculates a minimum flow requirement automatically to the deaerator to prevent the pump from overheating and causing internal damage. Pump manufacturers will dictate a pump's minimum flow requirement. The ARC valve will be designed to flow normal capacities through the main valve and also size the bypass to handle the minimum flow. Additionally, the flow sensing element, a disc, also acts as a check valve to prevent reverse flow to the pump.
Calculate pump efficiency for submersible pump?
pump eff. = (pump dynamic head x pump flow)/(pump h.p x 3960)flow=gallon per minute
What is the difference between booster pump and lifting pump?
The circ pump is used to circulate the water thru the filter. The booster pump is for running the pool sweeper.
Who invented hand pump?
The hand pump was invented by the Ptolemaics or today known as the Egyptians.
Is there a optimal flow rate for maximum heat transfer when using a heat pump?
Yes there is an optimum flow rate. Kind of! The heat pump manufacturer will post on the internet or in the users guide what the maximum and mimimum flow rate through his heat pump should be. I take it that the optimum then, is anywhere within that range. My pump manufacturer prescribes 20 GPM to 70 GPM for the heat pump I will be using. Too low a flow causes the heat pump to overheat. Too high a flow is hard on system components. dburr
Which reverses the normal flow of thermal energy?
heat pump
What tool remove fuel pump from gas tank?
Normal hand tools.
How do you find the maximum and average velocities in the pipe as well as the volume flow rate?
Pump flow. You should know what is the hydraulic pump. Dubai is defined. Amount of fluid inthe hydraulic diameter of the pipe passes.

In the US and Canada is the flow from pool returns clockwise or counter-clockwise?
If you have your left hand on the skimmer basket or the inlet side of the pump, and you have your right hand on the return side of the filter or the clean water going back to the pool then the flow will be clockwise.

What is the flow of 5 hp motar pump?
The flow of 5 hp motor pump is around 90 GPM.
What is the difference between booster pump and lifting pump?
The circ pump is used to circulate the water thru the filter. The booster pump is for running the pool sweeper.
What it the flow rate of a gas pump?
The EPA limits gas station pumps to no more than 10 gpm. The average gas station pump is between 5 and 10 gpm.
What is the difference between normal flowrate and Actual flow rate?
Normal flow is 100% of the flow you actually expect. Rated flow is the maximum safety factor times the normal flow. i.e. for a maximum safety factor of 1.2 Normal flow = 100 gpm Rated flow = 1.2*100 gpm = 120 gpm Safety factors are applied to ensure a piece of equipment has some flexibility of operating conditions in its application. The minimum flow is the minimum safety factor time the normal flow i.e. i.e. for a maximum safety factor of 0.5 Normal flow = 100 gpm Rated flow = 0.5*100 gpm = 50 gpm If sized properly a pump specified in this way could operate at any point between 50 and 120gpm with no problems.
Which pump has high specific speed?
Axial flow pump has high specific seed. According to US unit Ns >10000 has Axial flow pump.
What is trochoidal pump?
The axial flow pump with a piston to move in a few.
