Answer :
Solution : Given Diameter of Cylinder = 7cm therefore radius of cylinder = diameter/2 = 7/2 = 3.5cm . One Liter = 1000cm^3 , therefore 192.5 litre = 192.5 *1000cm^3 = 192500 cm^3
now in 1minute it collects 192500cm^3 of water so in 1hour it collects 192500*60(1hour=60minutes)
now we have to find out the height ( rate of flow is same as height)
so volume of cylinder =3.14*r^2*h
so, 22/7*3.5*3.5*h=192500*60
h=300000cm =3km
so rate of flow =3km per hour
now in 1minute it collects 192500cm^3 of water so in 1hour it collects 192500*60(1hour=60minutes)
now we have to find out the height ( rate of flow is same as height)
so volume of cylinder =3.14*r^2*h
so, 22/7*3.5*3.5*h=192500*60
h=300000cm =3km
so rate of flow =3km per hour
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
