Pump pressure Definition and 17 Threads

Hello everyone, I’m working on a project where I need to use a cylindrical tube with a vacuum pump to suck in mechanical parts. The tube approaches the part, and the vacuum generated by the pump draws the part into the tube. I want to understand how to link the key parameters of the system: the...

I’m trying to calculate the system curve of an already existing plant, the complexity lies in having 2 different lines, each with its respective pump 1- A substance contained in a closed tank with a liquid level of 40 ft connected to pump 1. 2- a closed tank of pure water connected to pump 2...

A vacuum pump is mounted at ground level. The pump is connected to a tree of overhead pipework at a height of 20ft, connected to the pipework are 12 hose reels that can be attached to oil drain tanks. The client requests that the pump be sized so that sufficient vacuum can be achieved to suck...

Hello everyone, I am very interested in knowing the relation to determine the pressure required to push the water upstream. In the attached picture, water is filled inside a tank of volume V and air is constantly flowing inside the tank through an inlet with constant flow rate M. Water should...

This is a deep well & the dimensions of the bottom chamber is 5x1x5ft which holds 187 gallons. The pump is located in this chamber with a piston/plunger only going up to the top of this chamber at 5ft. The pump pushes 187 gallons into a 6inch diameter pipe which is 1000ft long = 1,470 gallons...

Based on my understanding, Top Tank Refilling Advantage: Atmospheric Pressure Disadvantage: High Head (Requires more distance, thus more Work since W = f x d) Bottom Tank Refilling Advantage: Low Head Disadvantage: High Static Pressure (Requires more Force, thus more Work since W = f x d)...

Consider a closed system (central heating). Before the pump is started the static pressure is 2.0 bars. Say the system head loss is 0.6 bars. When the pump starts, will the suction side pressure and the discharge pressure each read half the total head loss (1.7 and 2.3 bars)? Or will the head...

I was told recently that in a central heating system, the pressure on the suction side of the circulation pump should be at least equal to the static height of the system. I've never heard this stated before, and I don't intuitively get why this should be the case. If there is actually something...

I have a centrifugal pump 50 m above a vessel, I’m pumping water in at 4 bar gauge into this vessel. I then close a valve to cease pumping ensuring no air enters the system.My question is, if I now open that same valve to atmospheric air this time, will the water exit from the pipe through the...

I am also constructing a small boat as a test bed for a much larger houseboat. If we forget about practicality issues... and accepting that my BS econ degree from the 60's isn't helping me much, I have a simple question with a difficult answer I guess. 2 stage centrifugal pump. (Standard...

hi guys, what is meant by rated pressure and flow of a pump... Is that maximum pressure or flow..but then i have seen 150% of rated flow?? How is that possible ?? please clarify my doubts...

I am a little confused about the pressure and hose diameter relationship. Let's say I have a pump pumping at a given pressure; I connect a hose of a certain diameter and attach a pressure gauge to the other end of the hose and get a pressure reading. Now let's say if i conduct the same...

is there any equations that can be used for calculating required pump pressure for a horizontal running water pipe given the pipe length, cross-sectional area, required flowrate and frictional loss co-efficient?? is this possible or is more information required?

Homework Statement I am having trouble with calculating the required pump pressure in a horizontal water pipe, 3Km long. i know that the flowrate is 600Kg/s, average velocity 5.6m/s, cross-sectional area of pipe is 0.107143m^2 and losses due to friction average 0.002 per meter Homework...

A fountain designed to spray a column of water 11.5 m into the air has a 1.34-cm-diameter nozzle at ground level. The water pump is 2.75 m below the ground. The pipe to the nozzle has a diameter of 2.68 cm. Find the pump pressure necessary if the fountain is to operate as designed. (Assume...
