Question

water in a canal, 6 m wide and 1.5 m deep is flowing with a speed of 10 km/h. How much area will it irrigate in 30 minutes if 8 cm of standing water is needed?​

Answer 1

ANSWER:-❣❣⤵️⤵️

Width=6m

Depth=1.5m

Area of Cross-Section=1.5×6=9m^2

Speed of Water=10km/h

=1000/60=500/3 m/min

Area irrigated in 1 min=500/3×9=4500m^

Area irrigate in 30 min=1500*30=45000

Now,

Vol. of flowed Water=Vol. of Area irrigate

Distance=8cm=8/100m

Now, 45000=8/100×A

A=45000×100/8=562500m^2
