Question

26. Water in a canal, 5.4 m wide and 1.8 m deep, is flowing with a speed
of 25 km/hr. How much area can it irrigate in 40 minutes, if 10 cm of
standing water is required for irrigation?
​

Answer 1

Step-by-step explanation:

Given, breadth is 5.4m, height is 1.8m.

in 40 and 60min is 25/60×40 = 50/3

so, volume = l×b×h = 5.4×1.8×50000/3(change in m).

if 10cm is required then, it will be...

5.4×1.8×50000/3×1/0.1 = 1620000m³.

I hope it will be helpful..!!
