Water in a canal, 5.4 m wide and 1.8 m deep, is flowing with a speed of 25 km/hour. How much area can it irrigate in 40 minutes, if 10 cm of standing water is required for irrigation?

Hi !
Speed = 25 km/hr = 2500 m/hr
Volume of water flowing out of the canal in 1 hr (60 min) = 5.4*1.8*2500
= 24300 m³
Volume of water flowing out of the canal in 40 min = 24300*40/60
= 16200 m³
Height of standing water = h = 10 cm = 10/100 m = 0.1 m
Area irrigated in 40 min * h = Volume of water flowing out of the canal in 40 min
Area irrigated in 40 min = volume/height
= 16200/0.1
= 162000 m²
= 16.2 hectares
Area irrigated in 40 min is 16.2 hectares.
