Water in canal 6m wide and 1.5 m deep is flowing with a speed of 10 km per hour how much area will it irrigate in 30 minutes at 8 cm of standing water is needed?
Answer:-
Width of Canal = 6m
Depth of Canal = 1.5 m
Speed of water = 10 km/hr
= 1000/60 m/min
Volume of water in 1 min = 6 × 1.5 × 1000/60
= 1500 m³
Therefore, the volume of water in 30 min
= (30 × 1500) m³
= 45000 m³
Let the area of irrigated field be A m²
Therefore, volume of water from Canal in 30 min = volume of water in the field
= ) 45000 = A × 8/ 100
A = 45000× 100/8
A = 562500 m²
Hence, it irrigates 562500 m² in 30 min.
I hope it helps you ^_^
