# How much water can flow through a 2 inch copper pipe?

## How much water can flow through a 2 inch copper pipe?

Water Flow (GPM/GPH) based on Pipe Size and Inside/Outside Diameters

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

1-1/4″ | 1.25 – 1.36″ | 62 |

1-1/2″ | 1.5 – 1.6″ | 81 |

2″ | 1.95 – 2.05″ | 127 |

2-1/2″ | 2.35 – 2.45″ | 190 |

**What is the flow rate of a 1/2 inch copper pipe?**

1/2″ pipe will reasonably supply in the range of 7 gpm. Draw more than that, and velocity is out of spec ( bad for pipes) and pressure loss per foot of pipe increases.

### What is the maximum speed recommendation for water flow through copper pipe?

5 – 8 feet per second

The recommended maximum velocity for water in a copper tube system is 5 – 8 feet per second (fps) for cold water systems, 4 – 5 fps for hot water systems < 140º F, and 2-3 fps for hot water systems with a temperature greater than 140º F.

**How much water can a 3/4 copper pipe flow?**

3/4″ inch copper can deliver twice as much water at a fraction of the pressure drop as 1/2″ copper. EG: 1/2″ copper type K at 100 foot and 3 GPM has a pressure drop of 7.4 PSIG. 3/4″ copper type K at 100 foot and 3 GPM has a pressure drop of 1.4 PSIG.

#### How many GPM will flow through a 2 inch pipe?

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

1.25″ | 1.25-1.36″ | 62 gpm |

1.5″ | 1.50-1.60″ | 81 gpm |

2″ | 1.95-2.05″ | 127 gpm |

2.5″ | 2.35-2.45″ | 190 gpm |

**What is the GPM of a 1/2 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 |

## What is the maximum velocity in copper and copper alloy tube and fitting systems for hot water?

8 feet per second

Maximum velocities in copper and copper alloy tube and fitting systems shall not exceed 8 feet per second (ft/s) (2.4 m/s) in cold water and 5 ft/s (1.5 m/s) in hot water.

**What is the velocity of water in a pipe?**

What is a ‘good’ pipe velocity?

Fluid | Typical Pipe Velocity (m/s) |
---|---|

Water | 0.9 – 2.4 |

Carbon tetrachloride | 1.8 |

Chlorine, liquid | 1.5 |

Ethylene glycol | 1.8 |

### How many gallons per minute can flow through an inch and a quarter pipe?

Here are the average water flow rates based on typical municipal water lines: ½-inch pipe: 50 gallons per minute. ¾-inch pipe: 110 gallons per minute. 1-inch pipe: 210 gallons per minute.

**How do you calculate flow rate through pipe?**

The flow rate depends on the area of the pipe or channel that the liquid is moving through, and the velocity of the liquid. If the liquid is flowing through a pipe, the area is A = πr2, where r is the radius of the pipe. For a rectangle, the area is A = wh where w is the width, and h is the height.

#### How do you calculate water flow through a pipe?

Measure each height from the center of the pipe. To find the initial water flow, solve for v_1. Subtract P_1 and p_g_y_1 from both sides, then divide by 0.5_p. T_ake the square root of both sides to obtain the equation v_1 = { [P_2 + 0.5p(v_2)^2 + pgy_2 – P_1 – pgy_1] ÷ (0.5p) }^0.5.

**What is maximum flow through a pipe?**

For normal liquid service applications, the acceptable velocity in pipes is 2.1 ± 0.9 m/s (7 ± 3 ft/s) with a maximum velocity limited to 2.1 m/s (7 ft/s) at piping discharge points including pump suction lines and drains.

## What is the PSI of copper pipe?

According to the copper tubing handbook 1/2 copper pipe, type L, residential grade copper burst pressure is 200 psi @ 100 degree F. Burst at 85 PSI at 250 Degrees F. Steam pressure rating is 15 Psi. Copper does expand and contract under temperature.
