Question

Water flows through a cylindrical pipe of internal diameter 7 cm at 5 m per seC. Calculate () the volume in litres of water discharged by the pipe in one minute. (i) the time in minutes, the pipe would take to fill an empty rectangular tank ot size 4 m x 3 m x 2.31 m.​

Answer 1

Answer:

So, the volume of the water in 1 second through the pipe is given by calculating the volume of the cylinder with diameter 7cm and length 5m. Hence, volume through pipe in 1 second = 19250cm3 .

Answer 2

Answer:

We know 1 minute = 60 seconds.

So, the volume of water discharged in 1 second = 19250cm3 .

Hence, volume of water discharge in 60 seconds

=60×19250cm3=1155000cm3 .

Hence, the volume of water through the pipe in 1 minute is 1155 litres.
