Question

Rate of flow of water through a cylindrical pipe is 192.6 litre per minute find the rate in km per hour

Answer 1

Explanation:

Answer:

Step-by-step explanation:

Diameter of cylindrical pipe = 7 cm

∴ Radius of cylindrical pipe

Volume of water flows in 1 min = 192.5 l

∴ Volume of water flows in 1 hour = 192.5 × 60 × 1000 cm3 ......(1)

Let l be the distance covered by water in 1 hour

Volume of water that covers the diameter of 1 hour = πr2l .....(2)

(1) and (2) ⇒ πr2l = 192.5 × 60 × 1000

multiply the equation you will get the answer 3km

i.e. distance covered by water in 1 hr is 3 km

∴ Rate of flow of water = 3 km/hr
