In the flow triangle, speed is measured in what unit?

In the context of the flow triangle, speed is measured in inches per minute (in/min). This unit represents the velocity at which a fluid moves through a system, such as a pipe or duct. It is crucial for understanding how quickly the fluid flows, which can impact system performance, efficiency, and the overall design of fluid transport systems.

The other units mentioned are related to different aspects of fluid dynamics. For instance, cubic inches per minute refers to the flow rate, measuring the volume of fluid passing through a point in a given time. Psi (pounds per square inch) is a unit of pressure, indicating the force the fluid exerts over an area. Square inches, on the other hand, measure area and do not apply to the concept of flow or speed. Therefore, the correct focus on inches per minute for speed in the flow triangle highlights its role in assessing fluid velocity.
