Static head measures the total vertical distance that a pump raises water. It has two components: static lift and static discharge. Static lift measures the elevation difference between the water source and the
How to size piping for pump-discharge conditionsPumps characteristics, system requirements and equipment locations are the main factors in establishing the most economical size of the discharge piping from centrifugal pumps.Kern, Robert
Here’s what you need to clean your pond: A clean-out pump with approximately 25 ft. of discharge hose A high-pressure nozzle for your garden hose, or a power washer Garden shears for trimming plants A child’s swimming pool or a similar sized container to hold fish and any other critt...
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,...
Pump style.Pump air from the humidity generator’s chamber to the chilled mirror and back again. Again, watch for condensation in the tubing by keeping the dew point of the gas lower than ambient temperature. Tips for ensuring a successful humidity measurement ...
Water creates pressure or resistance, at predictable rates, so we can calculate pump head as the differential pressure that a pump has to overcome in order to raise the water. Common units are feet of head and pounds per square inch. (A pump characteristic curve calculator might offer ...
(the most common way to calculate your pregnancy due date is from the first day of your last menstrual period, which is typically two weeks before conception.) false positives are very rare, but negative pregnancy test results can be wrong – if you took the test too early, or if your ...
Normally there should be no load transferred to the pump inlet or outlet flanges via pipework, so in my opinion the mass of the motor, pump and pump base should be considered. Another point just looking at the photo's of the pumps, on the discharge side, the pipe work support connects...
These measurements are compared with the measurements of the device under test (DUT). The difference between the two measurements lets you calculate the error of the DUT measurements. The calibration process described here uses a mixed-flow humidity calibrator to generate and measure the humidity ...
5. Calculate Hp Plug all the predetermined values into the equation for Hp to calculate horsepower. For example, if the system had a pump with a known efficiency of 65 percent and the pump delivers 250 gallons per minute to a total head of 72 feet, the horsepower of the system is: ...
