Question

Or
Water running in a cylindrical pipe of inra
diameter 7 cm, is collected in a containera
the rate of 192.5 litres per minute. Find the
rate of flow of water in the pipe in km/h.

Answer 1

Answer:

Step-by-step explanation:

1 litre = 1000cm^3

192.5 litre = 192500 cm^3

Length of water flowing per minute

= 192500/area of cross section of pipe

= 192500/π×3.5×3.5 = 5000 cm

Speed = 5000 cm/min

= 5 m/min = 300 m/hr = 0.3 km/hr
