Final answer:
The easiest way to make class A foam in the Flow Mix Model 500 is by adding a certain amount of concentrate to the water tank. The amount of concentrate needed can be determined using a ratio relationship between the concentrate and the water.
Step-by-step explanation:
The easiest way to make class A foam in the Flow Mix Model 500 is by adding a certain amount of concentrate to the water tank. To determine the amount of concentrate needed, we can use a ratio relationship that exists between the concentrate and the water. Let's say that x represents the amount of concentrate in gallons:
x / 500 = A / 1
Where A is the desired concentration of class A foam. We can solve for x by cross-multiplying:
x = (A / 1) * 500
Therefore, the amount of concentrate needed to make class A foam is (A * 500) gallons.
