Steel tapes are not recommended for taking water-level measurements in the pumped well owing to rapid water-level drawdown and the possibility of cascading water in the well.
When taking manual measurements in the pumped well, be sure to secure the measuring device when sounding the well to prevent accidental entanglement with the pump.
Use our Fire Pump Test Hose Caclulator to estimate how many hoses will be required to test a particular pump. Simply enter the fire pump and test information below. The results are based on the maximum flow required and friction loss to the flow device. There is always the possibility of job factors or variables we did not consider. Please be prepared with additional equipment. The user assumes all liability for its use.
In reviewing any such application, the Department must determine if the proposed well(s) will adequately meet the needs of the applicant and if others who may rely on the same aquifer will be adversely affected. The requirements that follow have been designed to produce the accurate and complete information that is vital to these determinations and whether modifications to the application or conditions in a potential permit are required.
Pumping Tests can save considerable sums of money by enabling the design of dewatering systems or geotechnical design to be tailored to the ground conditions at the site and to the specific construction project requirements.
FIRE PUMP TESTING
Fire pumps provide water supply to fire sprinkler systems where the water supply pressure is too low or nonexistent. The field acceptance test is conducted on newly installed pumps and demonstrates that all the fire pump unit components perform according to manufacturers’ specifications as well as proving that the water supply is adequate. The annual fire pump flow test can identify deterioration of the fire pump or impairments to the water supply.
Participants will learn to use one dimensional flow theory to design an impeller, to design a volute, and to predict how pumps behave in series and in parallel. Also covered is a prediction of critical rotational speed of a pump shaft, shaft stresses, disk stresses, keyway stresses, and more.
Wastewater Pump Draw Down Calculator
Based on several of my previous Pumps & Systems articles, you probably know that I have major concerns about the off best efficiency point (BEP) operation of wastewater pumps. Last month, I revisited suction recirculation and its potential effects on wastewater pumps due to the rather large eye diameter to impeller diameter ratio.
A yield test consists of determining the balance between the maximum amount of water that can be pumped and the amount of recharge back into the well from the surrounding ground water. Testing is done by continuously pumping water from the well for an extended period. During pumping measurements are made of the amount of water flowing from the well and the amount the water level is lowered in the well itself. This is known as the well’s drawdown.
