Bowl Horsepower :

  • Bowl horsepower is the power required at the pump bowl shaft.
  • It delivers the required capacity against the total dynamic head.
  • The bowl assembly is the core of a vertical turbine pump.
  • Bowl efficiency represents the ratio of hydraulic output to input power.

Uses :

  • Used to estimate power requirements of pumping systems.
  • Helps in selecting pump and motor sizes.
  • Represents minimum hydraulic power required to move water.

Formula :

  • Bowl Horsepower = (Capacity × Total Dynamic Head × Specific Gravity) / (3960 × Bowl Efficiency)
