Your civil engineering firm has been contracted to lay water pipes for two streets in a new neighborhood. The pipes (that will connect to the city's main intersection) must be able to provide 2190 gallons of water per minute to the new homes being built. The design calls for two safety valves that are each known to leak 1.70% of the water passing through them. How many gallons per minute must the water department provide at the main intersection (before entering your two pipes)

The answer is 2227.23 gallons of water per minute.

The gallons of water per minute to be produced before entering the two pipes is 2190*1.70%= 2190*0.017, which will give us 37.23 gallons of water to compensate the leakage in the pipes.

The final answer is 2190+37.23= 2227.23 gallons of water.

This is the amount of what needed to pass through the pipes that will connect to the city's main intersection to ensure that 2190 gallons of water per minute enter the new home being built.

1. read the following excerpt from franklin d. roosevelt's "fireside chat 19":

on the other side of the picture, we must learn also to know that guerilla warfare against the germans in, let us say serbia or norway, us; that a successful russian offensive against the germans us; and that british successes on land or sea in any part of the world strengthen our hands.

remember always that germany and italy, regardless of any formal declaration of war, consider themselves at war with the united states at this moment just as much as they consider themselves at war with britain or russia. and germany puts all the other republics of the americas into the same category of enemies. the people of our sister republics of this hemisphere can be honored by that fact.  

the true goal we seek is far above and beyond the ugly field of battle. when we resort to force, as now we must, we are determined that this force shall be directed toward ultimate good as well as against immediate evil. we americans are not destroyers — we are builders.
