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?
The three numbers are 52, 53, 54.
52+53=105 105+54=159
Answer:
2134
Step-by-step explanation:
beacuse that is the wright answer
x is a variable which in math means an unknown number, since 2+2=4 the answer (If your trying to find what x is) would be x=4.
Assuming you have to create an equation...
s is what you have to figure out so it is the subject of the rule
s=
you now need to find out what to do with the other side
you are taking 50 FROM 80 so
s=80-50
s=30
your answer is 30
