Water supply pipe, diameter and flow drop?
 

I want to run a water supply from the house 3/4 inch riser to a piece of
additional land we have bought, a distance of some 100 or so metres. I
don't want a big flow drop, what sort of diameter pipe should I use
(thinking alkathene type pipe here), and where is the cheapest place to
order from, with some fittings? Thanks.

I think this will enable you to calculate the flow drop

but you will need to know what flow/pressure you currently have at the riser to read the answer off the graph.

I used 32mm for similar purpose, no loss of flow over 100M and much better
than the previous 15mm copper! didn't know about screwfix! got it from LBS
