Question

1. How many litres of water flow out of a pipe having an area of cross-section of 6 sq. cm in one minute,
if the speed of water in the pipe is 42 cm/sec?​

Answer 1

Answer:

To find : How many liters of water flow out of a pipe having an area of cross section of 6 sq. cm in one minute if the speed of water in the pipe is 42 cm/sec. Therefore, Volume of the water flowing out of the pipe in one minute is 15.12 litres.

Answer 2

Volume of the water flowing out of the pipe in one minute is 15.12 litres.

Step-by-step explanation:

To find : How many liters of water flow out of a pipe having an area of cross section of 6 sq. cm in one minute if the speed of water in the pipe is 42 cm/sec.

Solution :

Area of the cross section of pipe = 6 cm²

Speed of the water flowing out of the pipe = 42 cm/sec

Volume of the water flowing out of the pipe in one second = Area of the cross section × Speed of the water flowing out of the pipe

i.e.

Volume of the water flowing out of the pipe in one minute is given by,

We know that,

1 litre = 1000 cm³

1 cm³ = 0.001 litre

15120 cm³ =  litre

15120 cm³ = 15.12 litre

Therefore, Volume of the water flowing out of the pipe in one minute is 15.12 litres.

How many litres of water flows out of a pipe having an area of cross section 5 cm square in 1 minutes if the speed of water in the pipe is 30 cm per second
