water pressure calculating

[AnonymousImport]

can anyone tell me how do I calculate the water flow or water pressure in a 3/4 inch garden water tap. Need to be measured in litre

This may sound daft but its simple and it works.

Get a 1 litre container, turn the tap on full blast, fill the container and time it.
so for the sake of argument it takes 2 seconds to fill the container that is 3600 (seconds per hour) divided by 2 (in this case) = 1800 litres per hour.

Thank you for your post
I need to know how to calculate the kpa for a tap timer
I should have been more precise in my first post
the tap timer will handle 600 kPa
thanking you from Paul in Aust.

I did a search for KPa and i found the following
KPa Korean Pig assosiation (unlikely)
Korean peoples Army (unliklely)
Kilopascal (maybe, 2 differnt sites said this))

Obviously it is to do with your water requirement, but could you put it into perspective ? so I can have more of an idea as to what the correct one is.

KPascal (or Kilo Pascal) is a unit of pressure. 7 Kp is about 1lb per square inch. So, your 600Kp is about 90lbs per square inch. Its a hell of a long time since College, but I'm sure that's right. This probably doesn't help, but at least you know what one is. Any use?

Thank you for your post I was so desperate to find out how much water pressure there was in the garden taps as I have just bought two of those batery operated timers it has a max pressure alowable of 600 kPa the other one I bought has a min of 20 psi to operate
I have just borowed a meter from the local irrigation shop I have 320 kPa and 280 kPa when two taps are running.
Thank you all for your help at least I know the relationship of kPa and psi
