Question

The cross-section of a pipe is 4.8 sq.cm. If water comes out of the pipe at 30 cm/s, how much water is delivered in 1 second?

Answer 1

Answer:

144 cubic cm is the volume of water that is delivered vin 1 sec

Answer 2

144 cm³ water is delivered in 1 second

Step-by-step explanation:

Given: The cross sectional area of pipe = 4.8 cm²

Now the water comes out of pipe at the speed = 30 cm/s

Therefore as we know

$Speed =\dfrac{Distamce}{Time} \\\\\Rightarrow 30 =\dfrac{Distance}{1} \\\\\Rightarrow Distance = 30cm$

Therefore

The distance is the length of pipe = 30 m

Area

$text {Volume} =\text {cross sectional area} \times \text{length }\\\\\Rightarrow Volume= 4.8\times 30 = 144 cm^3$

Hence, 144 cm³ water is delivered in 1 second
