Application | Maximum Velocity | |
---|---|---|

(m/s) | (ft/s) | |

Cooling water | 1.5 - 2.5 | 4.9 - 8.2 |

Suction boiler feed water | 0.5 - 1.0 | 1.6 - 3.3 |

Discharge boiler feed water | 1.5 - 2.5 | 4.9 - 8.2 |

Also know, what is the maximum flow rate through a pipe?

Water Flow Capacity in Steel Pipes (sch 40)

Pipe Size | Maximum Flow (gal/min) | Head Loss (ft/100 ft) |
---|---|---|

2-1/2" | 75 | 4.1 |

3" | 130 | 3.9 |

4" | 260 | 4.0 |

6" | 800 | 4.0 |

Similarly, what is the maximum flow rate through a 1/2 pipe? Metric PVC Pipe

Assume Average Pressure. (20-100PSI) About 12f/s flow velocity | ||
---|---|---|

Sch 40 Pipe Size | ID (range) | GPM (with minimal pressure loss & noise) |

1/2" | .50-.60" | 14 gpm |

3/4" | .75-.85" | 23 gpm |

1" | 1.00-1.03" | 37 gpm |

Just so, how much water can flow through a 100mm pipe?

2 x 90mm **pipes can flow** alot more than a **100mm pipe will** take - ie 90mm storm **water will flow** around 3.5 litres per second at max - **100mm pvc will flow** around 4.5 litres per second.

How much water can a 1 inch pipe pass?

**1**-**inch pipe**: 210 gallons per minute. 2-**inch pipe**: 850 gallons per minute. 3-**inch pipe**: 1,900 gallons per minute.
