<PRE><B>Question 1136521</B>
Water flows through a 7cm diameter pipe at the rate of 4 meters/second. 
1. How many cm^3 of water flows the pipe in one seconds
Assuming 7 cm is the ID (inside diameter):
The volume is a cylinder 7 cm diameter and 400 cms long
{{{Vol = pi*r^2*h}}} cc per second.
====================
2. Express the flow of water as a rate in liters/minute
Conversion:
1 liter = 1000 cc
1 minute = 60 seconds
