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?
4 divided by 12 -3+4 divided by 6+3 divided by 4
Answer:
91.46m
Step-by-step explanation:
The length of 100 yard football field in meters.
From the dimension given,
1 yard = 3 feet
Therefore,
100 yard = x feet
1 yard = 3 feet
100 yard = x feet
X = (100 × 3) / 1
X = 300 feet.
But,
1 metre = 3.28feet
X metre = 300 feet
X = (300 × 1) / 3.28
X = 91.46m
Therefore, 100 yard football field is equal to 91.46m
Answer:
y = 6.5
Step-by-step explanation:
When triangles are similar, we can set up a proportion to compare the sides. I will have the "left" side on the bottom of the fractions, and the side I am solving for on the top.
[Cross multiply]
12y = 78
y = 6.5

Answer:
1. 12 ft
2. 42.86 ft
Step-by-step explanation:
1. 5/24 = 2.5/<em>x</em>
<em> </em>5x<em> </em>=<em> </em>60
<em> x = </em>12 ft
2. 5/<em>x</em> = 7/60
7<em>x</em> = 300
x = 300/7 = 42.857 ft
