As an expert in the field of fluid dynamics and mechanical engineering, I have a deep understanding of how vacuum systems work and how their performance is measured. Vacuum suction is a critical parameter in various industrial applications, including material handling, medical equipment, and vacuum cleaners. It's essential to have standardized units to measure and compare the efficiency and power of vacuum systems accurately.
When discussing vacuum suction, we often talk about two primary measurements: Air Flow and Vacuum. These measurements are interrelated and can be combined to determine the overall performance of a vacuum system.
Air Flow is typically measured in Cubic Feet per Minute (CFM). This unit describes the volume of air that passes through a given cross-section in a minute. It's a crucial factor in determining how quickly a vacuum can remove air (and consequently, debris or other materials) from a particular space.
Vacuum, on the other hand, is often measured in Inches of Water Lift (WL). This unit is a measure of pressure, specifically the amount of pressure that can support a column of water one inch high. It's a practical unit for vacuum measurements because it's relatively easy to visualize and measure in a laboratory setting.
To quantify the performance of a vacuum system, we can use the concept of Air Watts. Air Watts is a unit that combines both air flow and vacuum measurements to give a single figure of merit for the system's suction power. The formula provided in your reference material is a simplified way to calculate Air Watts:
\[ \text{Air Watts} = \left( \text{Air Flow (CFM)} \times \text{Vacuum (Inches of Water Lift)} \right) / 8.5 \]
This formula is useful because it allows us to compare the suction power of different vacuum systems on a level playing field, regardless of their individual air flow and vacuum specifications.
Now, let's address the reference to a "two-inch opening" in your material. The size of the opening through which air is drawn can significantly affect the air flow and, consequently, the vacuum's efficiency. A smaller opening increases the velocity of the air, which can lead to higher suction but may also restrict the flow, potentially reducing the overall air flow rate.
It's important to note that while the formula and units provided are commonly used, the actual performance of a vacuum system can be influenced by many other factors, including the design of the vacuum head, the power of the motor, and the system's overall configuration. Additionally, different industries may have specific standards and preferred units for measuring vacuum suction.
In conclusion, vacuum suction is a complex phenomenon that is measured using a combination of air flow and vacuum, with the resulting performance often expressed in Air Watts. Understanding these measurements is crucial for anyone working with vacuum systems to ensure that they are using the most efficient and effective equipment for their specific needs.

The suction and air flow are measured with the air flow being restricted by a two inch opening. The formula for Air Watts is as follows: (Air Flow * Vacuum)/8.5 = Air Watts. The Air flow is in Cubic Feet per Minute (CFM) and the Vacuum is in Inches of Water Lift.
