If sensitivity of an irrigation module is 0.5, then what percent variation in outlet discharge will be caused by 50 percent variation in canal water depth?
Show Hint
Sensitivity of outlet helps in evaluating how changes in canal water level affect the outlet discharge. A sensitivity of 1 means full change, less than 1 means partial change.
Sensitivity is defined as:
\[
\text{Sensitivity} = \frac{% \text{ variation in discharge}}{% \text{ variation in water depth}}
\]
Given:
Sensitivity = 0.5
% variation in water depth = 50% Step 1: Rearranging the formula
\[
% \text{ variation in discharge} = \text{Sensitivity} \times % \text{ variation in water depth}
\] Step 2: Substitute values
\[
% \text{ variation in discharge} = 0.5 \times 50 = 25%
\] Therefore, the variation in outlet discharge is \( \boxed{25%} \).
