Using bath water for watering - pressure problem

Hi
I am new to the forum. I am experienced veg gardener and keen to recycle bath waste to water my garden. I recently connected a stop and garden hose fitting to the bottom of my 40mm bath waste that drops about 3.5m from first floor. When I drain the bath I get a good flow at the hose fitting but as soon as I connect a normal garden hose (about 10m) the pressure drops to virtually nothing. My physics knowledge says that the water should have the energy from the drop to push it along the hose - but I must be wrong! Any thoughts / advice would be greatly appreciated.

Cheers

Phil

- Boundary Layer : As the water/liquid flows through your pipe/garden hose there is a resistance to flow at the interior surface of the Hose- this further reduces the
actual space that you get a true flow through 'pattern' this is marginally effected by every bend or twist in the pipe, further reducing flow !

My best advice is to add a settling basin to settle out any large fragments of Dirt, Lint and Skin particles prior to using your 'soak hose' and accepting the reduced flow
as a fact of life or as a penitence for the fast pace you wish this part of life would give you ! Any 'Chant' at this point is optional !

For the Craft ! Big AL
