Volts (E) = Amps (I) x Ohms (R)

Amps (I) = Volts (E) / Ohms (R)

Ohms (R) = Volts (E) / Amps (I)

R=Ohms, E=Volts, I=Amperes

.

POWER - AC CIRCUITS Eff. = Efficiency, PF = Power Factor, KW = Kilowatts, HP = Horsepower | ||||||
---|---|---|---|---|---|---|

Efficiency | = | 746 x Output HP Input Watts | 3ø KW | = | Volts x Amps x PF x 1.732 1000 | |

3ø Amps | = | 746 x HP 1.732 x Eff. x PF | 3ø Eff. | = | 746 x HP 1.732 x Volts x Amps x PF | |

3ø PF | = | Input Watts Volts x Amps x 1.732 | 1ø KW | = | Volts x Amps x PF 1000 | |

1ø Amps | = | 746 x HP Volts x Eff. x PF | 1ø Eff. | = | 746 x HP Volts x Amps x PF | |

1ø PF | = | Input Watts Volts x Amps | HP (3ø) | = | Volts x Amps x 1.732 x Eff. x PF 746 | |

HP (1ø) | = | Volts x Amps x Eff. x PF 746 | 1 KW = 1000 Watts | |||

POWER - DC CIRCUITS Eff. = Efficiency, HP = Horsepower | ||||||
---|---|---|---|---|---|---|

Watts | = | Volts x Amps | Amps | = | Watts Volts | |

HP | = | Volts x Amps x Eff. 746 | ||||

MECHANICAL Torque in lb. ft., RPM=Revolutions Per Minute, HP = Horsepower | ||||||
---|---|---|---|---|---|---|

Torque | = | HP x 5250 RPM Result is lb.ft. Multiply by 12 for lb.in. | HP | = | Torque X RPM 5250 | |

1 HP | = | 36 lb.in. @ 1750 RPM | 1 HP | = | 3 lb. ft. @ 1750 RPM | |

FAN AND BLOWER MOTORS CPM = Cubic Feet per Minute, Pressure in lb. / sg. ft., Eff. = Efficiency | ||||||
---|---|---|---|---|---|---|

HP | = | CFM x Pressure 33000 x Eff. | ||||

PUMP MOTORS GPM = Gallons per Minute, S.G. = Specific Gravity, Eff. = Efficiency of Pump | ||||||
---|---|---|---|---|---|---|

HP | = | GPM x Head in Feet x S.G. 3960 x Eff. | Head in Feet | = | 2.31 P.S.I.G. | |
