Question

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)

Answer 1

Answer: 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.
