Test Fuse Length Calculator

Formula

The formula to calculate the desired time fuse length (DL) is:

$DL = \left( \frac{TL}{TT} \right) \times DT$

Where:

Let's say the test length is 10 inches, the test time is 5 seconds, and the desired time is 20 seconds. Using the formula:

$DL = \left( \frac{10}{5} \right) \times 20$

We get:

$DL = 40$

So, the desired time fuse length ( $DL$ ) is 40 inches.
