Maths Homwork

[darkart]

Morning all just thought i would post some maths home work for you all to work out as i dont have a clue on how to do it.

Bit complicated and not sure if this can be calculated but here goes?

If a property is supplied with 3 bar cold mains water pressure what flow rate would that give you at the tap in litres per minute?

As i assume you should have at least 3 bar cold supply of water pressure on entry into the property?

You can not calculate this accurately unless you have precise details and even then it is not precise. Question is really: why on earth would you want to??

Your assumption is optimistic. You may have 3bar, but you are only guaranteed 1bar. The flow will depend on the pipework in the property and the taps used so you need to provide more information. Easier to measure it.

This isn't maths, it's engineering. IE you need to allow for the maximum variation of several factors, then add a contingency.

It's a bit like, using an electrical analogy, flow (current in Amps) = pressure (volts) divided by resistance(Ohms).

Answer - "It depends".

you may have 3bar static but you won't have 3bar working pressure.
