Water Meter Size Vs Pipe Size

Typical water meter sizes are.

Water meter size vs pipe size. 1 inch pipe less than 100 feet to a house is good. About 12 f s flow velocity. Larger diameter water lines create less friction. 5 8 meters are generally used on older homes where the service tubing size was 1 2.

5 for fixtures or supply connections likely to impose continuous flow demands determine the required flow in gallons per minute gpm l s and add it separately to the demand in gpm l s for the distribution system or portions thereof. 4 the listed minimum supply branch pipe sizes for individual fixtures are the nominal i d pipe size. About 18 f s flow velocity. Water supply fixture units wsfu and minimum fixture branch pipe sizes.

About 6 f s flow velocity also suction side of pump. Appliances appurtenances and fixtures not referenced in the table below shall be permitted to be sized by reference to fixtures having a similar flow rate and frequency of use. Size water line videos below. Velocity of water flow in a pipe.

Let s use the pipe flow calculator to determine the velocity and discharge of a plastic pipe 0 5 feet in diameter. Water line size determines the amount of water flowing from a pipe. 8 inch diameter water main supplies. Assume gravity to low pressure.

Assume high pressure peak flow. Divide the diameter by 2 to find the radius of the pipe. 5 8 3 4 1 1 1 2. Size water line tips.

A standard meter coupling for a 5 8 water meter has male npt pipe threads on one end and a swivel meter coupling nut with 1 2 awwa meter threads on the other. This is because the larger size water meter would be unable to accurately measure at low flow rates. Bigger is better if you want lots of water in a short time. A larger meter size than what is required could mean that a residential customer will pay less each billing period and the utility profits would be undermined.

The pipe is 12 feet long and the difference in height between the beginning and end points of the pipe is equal to 3 feet. It is fairly common for the meter to be one size smaller than the feed pipe to the house. Water flow gpm gph based on pipe size and inside outside diameters. Assume average pressure 20 100psi.
