Question

WATER IN A CANAL 6M WIDE AND 1.5 M DEEP IS FLOWING WITH SPEED OF 10KM/HR HOW MUCH AREA WILL IT IRRIGATE IN 30MIN IF 8CM OF STANDING WATER IS NEEDED

Answer 1

Hello Mate!

Converting speed km into m.

So, volume of water = 6 m × 1.5 m × 10,000 m/hr

= 90000 m³/hr.

Now 90000 m/hr volume of water is taking 30 mins or 30/60 hr time.

= 90000 m³/hr × 30/60 hr

= m³.

Now, volume of 45000 m³ water stands on some area of height 8 cm.

Area × 8/100 m = 45000 m³

Area = 562500 m² or 0.5625 sq. km

Have great future ahead!
