The formula d= 1/2 + 26 relates the nozzle pressure n (in pounds per square inch) of a fire hose and the maximum horizontal distance the water reaches d (in feet). How much pressure is needed to reach a fire 50 feet away?

Pressure needed to reach a fire of 50 feet way.

Step-by-step explanation:

Given:

⇒ nozzle pressure n (in pounds per square inch) of a fire hose

⇒ maximum horizontal distance the water reaches  (in feet)

We need to find the nozzle pressure of a fire hose when distance is 50 feet.

Solution:

Now we can say that;

Substituting the value of d in above equation we get;

Subtracting both side by 26 we get;

Multiplying both side by 2 we get;

Hence pressure needed to reach a fire of 50 feet way.
