flow rate (gph gpm lph lpm) is how many units (gallon/liters) the pump can move in a specific rate of time. pressure is measured in psi (pounds per square inch). this comes into play when you are moving fluids beond 1ft called the pumps "head" or the distant the pump can move a fluid strait up. most pond pumps have a head height of 3-4ft where high pressure (psi) pumps, such as a fuel pump can move the same liters 15ft strait up.
a 5psi pump with a flow rate of 1gpm can move water 12" high at a rate of 1 gallon of fluids in 1 minute (not real values just an explanation)
where as a 50psi pump with a rate of 1gpm can force a fluid 25ft up at a rate of 1 gallon per minute
the viscosity and diamiter of Plumbing also affect these values you will get a higher head rate and increase psi with a smaller diamiter outlet than a larger but a larger diamiter outlet will decrese psi (head) but increase the flow (gpm,gph, lpm,lph)

Does a pump produce flow or pressure?
Actually, its the exact opposite. Newton's first law of motion states that every object will remain at rest unless an outside force acts upon it, proving flow is only caused by an outside force. This force may be gravity or contact with a spinning pump impeller. Pressure is a force per area and the cause of fluid motion. The amount of pressure applied to a fluid determines the flow. _____________________________________________ The paragraph is basically correct for most applications. The previous first line is not, and I've eliminated it. The actual answer depends on the type of pump. The most common pump is a centrifugal pump. This type of pump basically accelerates the fluid (adds velocity). If you measure the pressure at a point at the outside of the volute of a normally operating centrifugal pump, it would be very low as the velocity is high there. At a point in the pipe slightly downstream of the pump, the pressure would be higher as the velocity is lower and the overall energy content of the fluid is essentially the same. The pressure and velocity are related in that both are components of the energy inherent in the fluid. This relationship is the Bernoullli equation. But there are other types of pumps besides centrifugal. I'm thinking positive displacement pumps, like piston pumps, gear pumps, or peristaltic pumps. These pumps increase the pressure of the fluid directly, which results in higher flow in the system as a whole. They are less common than centrifugal pumps, but positive displacement pumps are a very significant share in the world of "pumps". ________________________________________________
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.
What is pressure flow?
The pressure flow theory describes the movement of food through the phloem. The theory was originated by Ernst Munch.
What are the uses for a hydraulic pump?
Hydraulic drive systems like gear pumps, rotary vane pumps, screw pumps, bent axis pumps etc. One real life example of hydraulic pumps is the brake master cylinder in a car. You also see hydraulic pumps in excavators.
What is mean by cold chamber die casting machine?
cold chamber die casting machine can be divided into the direction of the direction of the flow of fluid in the hydraulic system used to control or regulate the pressure and flow valves, pressure valves and flow control valve three categories. A same shape as the valve, because of the different mechanisms of action have different functions. Pressure valve and flow valve with a throttle effect of the flow passage cross section to control the system pressure and flow direction valve replacement of the flow passage control the oil flow direction.
What is relation between mass flow rate and discharge pressure in reciprocating compressor?
These have a inverse relation. You will need to know the discharge and the incoming pressure in order to find out the mass flow rate.
Does pump create pressure?
No. Pumps create flow. Resistance to flow creates pressure.
What establishes the amount of pressure a hydraulic pump will generate?
Hydraulic pumps do not develop pressure. Pumps can only develop flow. To obtain pressure in an hydraulic system, restriction to flow must be introduced. In order to control pressure, pressure relief valves are used. These valves, simply put, employ spring pressure acting on a check ball that resists the flow of oil. Most pressure relief valves are adjustable within a given range so that system pressure is also adjustable.
What is a pressure differential?
its pressure between suction and discharge flow...
Does artery pumps blood at high pressure?
(you mean "do areteries pump blood at a high pressure?") areteries do pump blood at high pressure when they are entering the heart.but it flows out at a slower pressure as it is entering the capillaries.the arteries a very narrow tubes and so for a successful flow the blood pumps into the heart quickly.
What is the relation between light and current?
One relationship is that both can flow in vacuum.
What is the relation between viscosity and flow-ability of a material?
The higher the viscosity, the lower the flow-ability of a material.(Viscosity=internal resistance to flow)
What is the relation between viscosity and flow ability of a material?
The higher the viscosity, the lower the flow-ability of a material.(Viscosity=internal resistance to flow)
Why would your log splitter have limited pressure?
If your log splitter has less pressure then when you bought it then you may want to take a look at the pump. Most pumps are two stage pumps and it may have got damaged. Another thing to look at is the valve, the valve may be restricting flow not giving you the pressure you need.
What is the relationship between flow rate pressure?
With the increase in flow rate the velocity of the fluid increases. and with the increase in velocity the pressure decreases, because there will be pressure drop (Refer Bernoulli's Theorm). So with increase in Flow rate the pressure decreases.
What is the difference in working between axial flow pumps and mixed flow pumps?
In axial flow pumps, fluid enters and exits along the same direction parallel to the rotating shaft giving high flow rates and low head. In radial flow pumps, fluid enters and leaves perpendicular to the rotating shaft giving high head and low flow rates. Thus, in mixed we have combined of both axial and radial.i.e.Liquid will go behind the impeller at certain angle between 0-90degrees normally below 45degree.Mixed flow replace axial when we require head not provided by the axial pump as we have to lift water from a water a lower level and then discharge it. physically,mixed flow can be identified by bellmouth(diverging converging shape) which shows its between axial and radial.

What is the relation between current and thikness of conductor?
The thicker the conductor, the less the current that will flow through.
