# Pipes

Water pipe has a cross-section 1087 cm2. An hour has passed 960 m3 of water. How much water flows through the pipe with cross-section 300 cm2 per 9 hours if water flow same speed?

Correct result:

V2 =  2384.5 m3

#### Solution:

$V_2 = 9 \cdot \dfrac{ 300} { 1087} \cdot 960 = 2384.5 \ \text{m}^3$
