Question from Tom: I need a slope of 2 inches every 30 feet what is the percentage to put on my pipe lazer. thank you |
Hi Tom,
$30$ feet is $30 \times 12 = 360$ inches so the pipe rises (falls?) 2 inches in 360 inches and hence the slope is
\[\frac{2}{360} = 0.00556\]
which as a percentage is 0.556%.
I hope this is what you need.
Write back if you need more assistance,
Penny
