**15 mm and 22 mm**

Here’s how to determine pipe size by simply measuring the OD. Copper. The nominal size of copper pipe, whether supply lines or DWV, is always 1/8 inch less than the OD measurement. For example, copper pipe that measures 5/8 inch OD, is called 1/2- inch pipe.

Thereof, How do I calculate pipe size?

The equation for pipe diameter is the square root of 4 times the flow rate divided by pi times velocity. For example, given a flow rate of 1,000 inches per second and a velocity of 40 cubic inches per second, the diameter would be the square root of 1000 times 4 divided by 3.14 times 40 or 5.64 inches.

Subsequently, question is, How do you fix a 1/2 inch copper pipe?

Also, What is the difference between Type L and M copper pipe?

The key difference between types L and M is their pressure rating and wall thickness. The most common copper pipe sizes are ½ and ¾ inches. Type M ½ inch measures 0.028” in wall thickness whereas type L ½ inch measures 0.04” in wall thickness.

## Which is thicker L or M copper pipe?

Type M and L Differences The main difference between type M and L is the wall thickness and pressure rating. The two most common sizes are half-inch and three-quarter-inch. Type M half-inch pipe has a wall thickness of 0.028 inches while type L is 0.040 inches.

## Is copper pipe measured ID or OD?

The nominal size of copper pipe, whether supply lines or DWV, is always 1/8 inch less than the OD measurement. For example, copper pipe that measures 5/8 inch OD, is called 1/2- inch pipe. The ID varies because wall thickness varies. Type K has the thickest wall, followed by Type L, Type M and DWV.
