How to Calculate the Capacity of the Head in Feet
- 1). Multiply the density of the fluid by the acceleration due to gravity. For example, multiply the density of water (1.0 kilograms per meter cubed) by the acceleration due to gravity of 9.81 meters per second gives a result of 9.81 Newtons per meter cubed. Call this result A.
- 2). Divide the gauge pressure of the head by result A. For example, if the gauge pressure of the head is 200 Pascals (Pascals being the unit of measurement for pressure), then dividing this by result A gives 20.4 meters. This is the capacity of the head.
- 3). Convert the result in meters to feet by multiplying the result by 3.33 feet per meter. Concluding our example, multiplying 3.33 feet per meter by 20.4 meters gives 67.9 feet. This is the capacity of the head in feet.
