Can anybody help me? :)

Hi The minimum pressure acceptable in South African water reticulation systems is 24m. The maximum pressure acceptable is 900 kPa. http://www.mangaung.co.za/docs/Regulations-Water-Conservation.pdf I need to write write a training manual for the waterworks department, and I need to...

Thank you for your help

Thanks for the reply, So would a way that I could explain it be that if the 'head' in a water pipe is 24m, that pressure would be enough to push that water 24m up at normal g? Could I say that a head of 10 m is low pressure, and a head of 50m is high pressure. another way that I could say it...
