Water in canal 300cm wide and 120cm deep, is flowing with a speed of 20kmph how much area will it irrigate in 30min with 2cm standing water

Answer 1

Answer:

HERE IS YOUR ANSWER

Step-by-step explanation:

Width 300cm=3m

depth 120cm=1.2m

speed of canal 20km/h

20×1000m/h

vol. of water flow in 1 hour = width of canal ×depth of canal ×speef of canal water

3×1.2×20×1000=72000m3

in 20 in vol. of water flows = 72000×20÷60=24000m3

area irrigated in 20 min 2400÷0.08=300000m2

30 hectare
