Solving For Brake Horsepower

Note: Equation for water at 68 Fahrenheit. Usually, temperature correction for water is negligible.

discharge or flow rate (Q) = 0 = 0 gallon/minute |

total head (H) = 0 = 0 foot |

pump efficiency (n) = 0 = 0 |

brake horsepower (WHP) = NOT CALCULATED |

Net Positive Suction Head and Cavitation

Where

WHP | = | water horsepower |

Q | = | flow rate or discharge |

H | = | total head |

n | = | pump efficiency |

BHP | = | brake horsepower |

NPSH | = | net positive suction head |

V | = | velocity of fluid or liquid |

p | = | impeller inlet pressure |

p_{v} | = | vapor pressure of fluid or liquid |

SW | = | specific weight of fluid or liquid |

g | = | acceleration of gravity |
