    …ummmmmm, I guess I was just looking for a simple “ballpark” answer. I am replacing 450′ of 3/4″ pipe with either 1.25″ or 1.5″ pipe – I dunno the type – it’s what people here in the US call “black poly” – you can find it at Home Depot, etc… The inner surface finish of all pipes is the same – same material, vendor, etc…


    Ok here we have some information 3/4 pipe at 50 PSI will give you a “flow rate” in Velocity around and a GPM flow around 34.44 GPM

    For a 1/1/2 ” line at 50 PSI you would have a GPM flow around 140 GPM

    This is close as I can get from the top of my head with out looking at charts
