the cross section of a cylindrical pipe is 35 cm square water is flowing out of this pipe at the rate of 20 cm per second find the volume of the water that flows out of the pipe in 2 minutes
Answers
Answer:
volume of the water flowing the pipe in one second=area of the cross section of the pipe x water flowing in one second
pipe in one second= 35 ×20cm =700cm2
volume of water flowing out of the pipe in 2 minutes I. e 120 second.
700× 120cm2
84000 cm2
84000cm2= 84000÷ 1000
=84 liter
hence volume of the water flowing out of the pipe in 2 minutes is84 liter
Answer:
Volume of the water flowing out of the pipe in 2 minutes is 84 litres.
Step-by-step explanation:
Given:
Area of cross section = 35 cm²
Speed of water flowing out of the pipe = 20 cm per second.
To Find:
Volume of the water flowing out of the pipe in 2 minutes.
Solution:
Volume of the water flowing out of the pipe in one second = area of the cross section of the pipe x water flowing out in one second
⇒Volume of water flowing out of the pipe in one second = 35 x 20 cm
= 700 cm
∴Volume of water flowing out of the pipe in 2 minutes i.e. 120 seconds = 700 x 120 cm
= 84,000 cm
∵ 1000 cm = 1 litre
∴84,000 cm = litres
= 84 litres
Hence, Volume of the water flowing out of the pipe in 2 minutes is 84 litres.
