## How many gallons does a 8 pipe hold?

600 = 30,159.29 cubic inches. Hence the volume in US gallons is 30,159.29/231 = 130.56 gallons.

## How many gallons are in a foot of pipe?

## How do you calculate the flow rate of a pipe diameter?

With a radius, for instance, of 0.05 meters, 0.05 ^ 2 = 0.0025. Multiply this answer by the pressure drop across the pipe, measured in pascals. With a pressure drop, for instance, of 80,000 pascals, 0.0025 x 80,000 = 200. Multiply the constant pi by the answer to Step 1: 3.142 x 0.0025 = 0.00785.

## Is 3/4 PEX big enough?

In general, the greater the distance from the manifold to the fixture, the wider the PEX tubing should be. A 3/8-inch line is sufficient for lengths up to 250 feet; 1/2-inch line will deliver adequate water pressure up to 350 feet; and 3/4-inch tubing is necessary to run a 500-foot line.

## How many fixtures can a 1/2 water line feed?

According to Table 6-6 (610.4), at 30-45 psi you can supply 3 wsfu with ½” pipe with a developed length of up to 100′. 46-60 psi you can have a developed length of up to 200′, and greater that 60 psi can go up to 300′. At 40′ or less with 30 psi, ½” pipe can supply 6 wsfu.

## How long can you run a half inch water line?

A 3/8-inch line is sufficient for lengths up to 250 feet; 1/2-inch line will deliver adequate water pressure up to 350 feet; and 3/4-inch tubing is necessary to run a 500-foot line.
