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...
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 is to test it yourself. Don't be fooled by false advertising any longer–follow these steps...
Calculating your macros is tied into three things: your lifestyle, your health, and your individual metabolic rate. We’ll look at how these link to your macros when we discuss the calculation method. So, let’s look at how you calculate your macros. HOW TO CALCULATE YOUR MACROS The equat...
Define a pipeline flowing system to begin the calculation. As an example, if water has to be pumped through a 2-inch Schedule 40polyvinyl chloride (PVC) pipefrom a well to a pond 400 feet away,calculatehow many gpm the system is delivering. The pressure gauge on the pipe at the well h...
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,...
Still, calculating a general fat-burning heart rate is based around two different things: your max heart rate and resting heart rate. To calculate your maximal heart rate, start by subtracting your age from 220. So, if you're 30 years old your maximal heart rate should be roughly 190, an...
First, by looking at the net positive suction head required (NPSHr) curve of the pump. This is a calculation of how much absolute pressure is needed at the inlet to keep the system from cavitating. Second, calculate the NPSH available (NPSHa). This value represents the absolute...
If you want to run faster with less effort (who doesn’t?), it’s time to learn more about how to increase your VO2 max. We have all the info you need.
The first thing you need to do is calculate how many calories you should be consuming, and how much you’re burning realistically based on your height and weight. A calories burned calculator should help you determine your required caloric intake, so you can structure your meal plan accordingly...
the fitting to get the measurement. Many PVC fittings are slightly tapered and won’t allow you, in most cases, to fully seat “dry” pipe. We’ll explain this in detail when we get into how to glue PVC. The take-away is to use the tape measure to calculate the depth of the ...
