for canal
width= 5.4 m
depth=1.8 m
speed of water=25km /hr
25000 m / hr
25000/60x40=16666.66 m in 40 mins
vol of canal = area irrigated
LxBxH=LXBXH
5.4x1.8x16666.66=LXBX10/100
161999.9352x100/10=area
1619999.352 m^2= area

Given,
Breadth = 5.4 m
Height = 1.8 m
Speed of canal = 25 km/hr
Length of canal in 1 hour = 25 km
Length of canal in 60 minutes = 25 km
Length of canal in 1 min = 1/60 * 25
Length of canal in 40 min = 40/60 * 25
= 16.67 km
= 16670 m
Volume of canal = Length * Breadth * Height
= 16670 * 5.4 * 1.8 m³
Volume of water in canal = Volume of area irrigated
Volume of water in canal = Area irrigated * Height
16670 * 5.4 * 1.8 m³ = Area irrigated * 10 cm
16670 * 5.4 * 1.8 m³ = Area irrigated * 10/100 m
16670 * 5.4 * 1.8 * 100 / 10 = Area irrigated
Area irrigated = 1620324 m²
Area irrigated = 1620324/10000 hectares
= 162.0324 hectares Ans.
Ans.) 162.0324 hectares area can it irrigate.
Breadth = 5.4 m

Length of canal in 1 min = 1/60 * 25
Length of canal in 40 min = 40/60 * 25
= 16.67 km

Volume of canal = Length * Breadth * Height
= 16670 * 5.4 * 1.8 m³
Volume of water in canal = Volume of area irrigated
Volume of water in canal = Area irrigated * Height
16670 * 5.4 * 1.8 m³ = Area irrigated * 10 cm
16670 * 5.4 * 1.8 m³ = Area irrigated * 10/100 m
16670 * 5.4 * 1.8 * 100 / 10 = Area irrigated
