A river 2m deep and 45m wide is flowing at the rate of 3km per hour. Find the volume of water that run into the sea per minute.
Given that rate of flow 3km/h
Depth (h) of river =2m
Width (b) of river =45m
Area of cross-section of river=Depth×width
Rate of flow 3 km/h=3×100060
Volume of water is flowing in cross-section in 1 minute is=90×50=4500m3/minute
A river 2 m deep and 45 m wide is flowing at the rate of 3 km/h. Find the quantity of water that runs into the sea per minute.
