this formula is used to determine gpm (gallons per minute) of flow with a known hose diameter (d) and nozzle pressure (np). The constant (29.7) is consistent when figuring flow with in gallons with a know pressure expressed in psi (pounds per square inch).
Scenario example: a firefighter is using a handline to fight fire with an 1 3/4 inch line with a nozzle pressure of 100 psi. How much water is the firefighter flowing when fighting fire?
Answer:
(0,-2)
Step-by-step explanation:
First we find the equation of the line passes through and
.
The slope of the line is
So by the point slope formula the equation of the line is
When we have
.
Therefore the line joining the two points cuts the y-axis at (0,-2).
