Question

vertical gate in an irrigation canal holds back 12.2 m of water. Find the average force on the gate if its width is 3.60 m. Report your answer with proper units and 3 sig figs.

Answer 1

The right solution is "2625 kN".

Step-by-step explanation:

According to the question,

The average pressure will be:

=
`density* g* (h)/(2)`

By putting values, we get

=
`1000* 9.8* (12.2)/(2)`

=
`1000* 9.8* 6.1`

=
`59780`

hence,

The average force will be:

=
`Pressure* Area`

=
`59780* 3.6* 12.2`

=
`2625537 \ N`

Or,

=
`2625 \ kN`
