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.
