Question

water in a Canal 30m wide and
12m deep
is flouring at the rate
of 100 km per hour How much
to water
will fall into the land
for irrigation in 1 minute? Convert
the
Capacity of water in litres.​

Answer 1

Step-by-step explanation:

Velocity of water=20Km/h

Water in the canal forms a cuboid of breadth = 12dm=1012m=1.2m

Height = 30dm=1030m=3m

Length = Distance covered by water in 30 minutes

            = Velocity of water × time

         =20000×6030=10000 m

Therefore,

Volume of water flown in 30 min = lbh=(1.2×3×10000)=36000 m3

Suppose area irrigated be A m2. Then,

A×1009= Volume flown in 30 minutes

A×1009=36000

A=400000 m2

Hence, area irrigated =400000 m2
