PROBLEM. $3$

A current meter is used to get datare lating to evaluation of discherge al a gauging station of a river. The numbers of revelution perminute at $0\mathrm{.}2$ and $0\mathrm{.}8$ times the depth of water of the niver cross section are as shown in the table given below $(d=$ depth of flow$).$

Compute $($find$)$ the total dischage for this section.

The calibration of the currentructer is yiven as

$V=0\mathrm{.}06+0\mathrm{.}5N,$ here in $N$ is in rev$/$s and $V$ is in $\frac{m}{s}.$
