Question

WATER IS FLOWING AT THE RATE OF 7 m/s THROUGH A CIRCULAR PIPE WHOSE INTERNAL DIAMETER IS 2cm INTO A CYLINDRICAL TANK THE RADIUS OF WHOSE BASE IS 40 cm DETERMINE THE INCREASE IN WATER LEVEL IN 1/2 hrs????

Answer 1

Water is flowing at the rate of 7 m/s.

o length of pipe in which the water has traveled,

h = 7(1800) = 12600m

Radius of the pipe(r)= 1cm

Radius of the cylinder(R)= 40 cm

let the height of the water in the tank H

So,

Volume of water coming from the pipe = Volume of water in the cylindrical tank.

πr^2h = πR^2h

H = {(0.01)^2 X 12600}/(0.4)^2 = 7.875m (ans)

if it help you then plz mark it as brainliest ans.

Answer 2

Answer:

h=7.875 mtrs
