Question 4
An iron tank 5 m × 3 m is filled with water upto a height of 4 m. What surface area of the tank is at a higher risk of corrosion?
Question 5
How much water flows per hour through a pipe of radius 14 cm, if water flows at 10 km/h? Take π = 22/7.
616 cu. m.
618 cu. m.
614 cu. m.
620 cu. m.
Ans: a
In one hour, a water column of length 10 km is delivered through the cylindrical pipe. The equivalent volume is ${22 × 14 × 14 × 10 × 1000}/{7 × 100 × 100}$, which can easily be cancelled to get 616 cu. m.
