[pahunt16]

Can you help

we are having an all weather football pitch installed and there is a question over the fall for drainage. it states that the fall should not exceed 1% over the total length.

my question is what is the maximum fall at 1% if the pitch is 36 metres long please

welcome to pf!

hi pahunt16! welcome to pf!

it's exactly what it says …

the fall is 1% of 36 metres, which is … ? ​

I have worked out the fall as .36 metres which equates to a fall of 360mm or 14" over the length.

Can you confirm I am correct in saying that one end of the pitch will be 14" lower than the other.

Just looking for confirmation please

Yup!

1° of 36 m is 36 cm (that's why some people like the metric system so much!),

and 2.54 cm = 1" (exactly),

so 36 cm = (36/2.54)" = 14"
