Field Efficiency
Field Efficiency :
  • Field efficiency is usually used to evaluate the performance of pumping the water.
  • High-quality pumps that are well-maintained can achieve efficiencies of 90% or higher, while smaller pumps tend to be less efficient.
  • In general, if you take good care of your pumps, you should be able to achieve 70-90% pump efficiency.
  • Motor efficiency is also an important factor here.
  • Pump efficiency is defined as the ratio of useful hydraulic power delivered to the fluid to the power input at the drive shaft.
  • The further away your pump is from its best energy point, the more energy it will use and the less reliable and efficient your system will be.
  • This increases operating costs and can cause maintenance issues.
Formula :
  • The formula for the calculation is given below.
  • Field Efficiency = (Capacity * Field Head * Specific Gravity) / (3960 * Break Horsepower).
  • Beside the formula this calculator works.
How to Calculate ?
  • First, Enter the Capacity (gal / min). Then,
  • Second, Enter the Field Head (ft). Then,
  • Third, Enter the Specific Gravity. Then,
  • Fourth, Enter the Break Horsepower (Motor Load). 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.
