 Field Efficiency : Driver Efficiency : Result :
##### Definition :
• It means the emission reduction, expressed as a percentage that results from the combined effect of capture and control of affected pollutants.
• It is what you would use to determine the amount of wasted energy loss throughout a pump, which can be defined as the ratio of the actual power output to the actual power input.
• It is defined as the ratio of useful hydraulic power delivered to the fluid to the power input at the drive shaft.
• Many medium and larger centrifugal pumps offer eff of 75 to 93 percent and even the smaller ones usually fall into the 50 to 70 percent range.
• Large AC motors, on the other hand, approach an efficiency of 97 percent, and any motor ten horsepower and above can be designed to break the 90 percent barrier.
• Then, it is the efficience of the pump in turning input shaft power (from the motor) into useful power output to the fluid (Hydraulic Power)
##### Uses :
• It can be used to determine how much drive power is needed for a hydraulic pump.
• Then, The types are allocative, productive and dynamic.
##### Formula :
• The formula for the calculation is given below.
• Overall Efficiency = (Field * Driver).
• Beside the formula this calculator works.
##### How to Calculate ?
• First, Enter the Field Eff. Then,
• Second, Enter the Driver Eff. Then,
• Click “Calculate” to get the result and then if you want to clear values Click “Reset” in addition to clear the values.
• Finally, follow these steps to get the result.
