Click For Summary
The maximum allowable fall for a 36-meter football pitch is calculated at 1%, resulting in a total drop of 0.36 meters, or 360 mm, which is equivalent to approximately 14 inches. This means one end of the pitch will be 14 inches lower than the other. The discussion confirms the calculations are correct, emphasizing the ease of using the metric system for such measurements. Participants agree on the accuracy of the conversion between centimeters and inches. Proper drainage is essential for the installation of the all-weather pitch.

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! :wink:

it's exactly what it says …

the fall is 1% of 36 metres, which is … ? :smile:​
 
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! :biggrin:

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" :smile:
 

Thread 'Area of Overlapping Squares'

Here is a little puzzle from the book 100 Geometric Games by Pierre Berloquin. The side of a small square is one meter long and the side of a larger square one and a half meters long. One vertex of the large square is at the center of the small square. The side of the large square cuts two sides of the small square into one- third parts and two-thirds parts. What is the area where the squares overlap?
