If you can see the fluid flowing, you can measure its velocity, and that means all you need is the area through which the fluid is flowing to calculate the flow rate using the formula Q = A × v. If the fluid is flowing through an orifice or a clear tube, o...
The required pumping speed of the backing pump is calculated from: (2.41a) Example how to calculate the pumping speed In the case of a diffusion pump having a pumping speed of 400 l/s the effective pumping speed is 50% of the value stated in the catalog when using a shell baffle...
Calculate the cross-sectional area for both pipe one and two by multiplying the square of the radius by the number pi, 3.14. In the example calculation that follows, the symbol "^" represents an exponent. Performing this step, you have for the first pipe: 3.14 x (2.5 inches )^2 or 19...
How to Calculate the Water Inflow Rate = Calculate the Necessary Sump Pump Capacity Typically most of us just buy a 1/4 hp or 1/2 hp sump pump and throw it in the pit and see what happens. But you can guesstimate the rate at which water is flowing into the sump pit by knowing the...
This article will describe parts of the compressor map, how to estimate pressure ratio and mass flow rate for your engine, and how to plot the points on the maps to help choose the right turbocharger.
Define the head loss application. In this example, a water pump in the basement of a 10-story building supplies domestic water to every floor. Assuming that each floor in the building represents 12 feet of height, you can calculate the head loss due to elevation and subtract it from the ...
How To Calculate The CFM Of An Air Compressor Things Needed Calculator Pen Paper Stop watch CFM stands for cubic feet per minute. Oftentimes the true rate of an air compressor is misrepresented by manufacturers. Because of this, the only way to determine the real CFM of your air compressor ...
To evaluate the performance of an existing compressor, the objective is to calculate the compressor efficiency (η) and power requirement. Known and measured properties are: a.Standard condition gas volume flow rate (qS) or gas mass rate () ...
Ourwater volume calculatorcan be used to calculate sump water volume, just like a tank. Remember, most sumps only run about 50-60% full of water when in operation. One major point to consider when deciding on a sump. The bigger the better is common advice from more experienced hobbyists ...
So what is GPM, and how do you calculate it? Browse Our Pumps What Is GPM? GPM stands for gallons per minute and is a measurement of how many gallons a pump can move per minute. It is also referred to as flow rate. GPM is variable based on another measurement known as the Head,...
