I have 1/2" water lines and a well. The water pressure is always between 30 and 50 PSI. How do I figure out the flow rate??????

    Flow in 1/2 inch copper tube

    Flow is a function of pressure-drop, which depends on piping length and any other restrictions such as valves.

    Check the Copper Tube Handbook

    A simple

    but effective method is to just put a measured bucket under any faucet, open wide and time it.

    A two gallon bucket filled by a tub in two minutes will be 1 gpm. Etc., Etc.

    Thanks for the math refresher, Brian.

    I think you mean

    a one gallon bucket filled in 30 sec's is 2 gpm :O)

    Maybe we have different buckets in Swampland :)
