Final answer:
In physics, static and flow pressures can be measured and compared. Their values can be posted on a tag to indicate changes before and after a specific event or condition.
Step-by-step explanation:
Physics
In physics, the subject of static and flow pressures can be studied. When discussing these pressures, it is important to understand that they can be measured and compared. The values of both static and flow pressures can be posted on a tag to indicate the changes that occur before and after a particular event or condition.
For example, in a fluid dynamics experiment, the static pressure refers to the pressure exerted by the fluid when it is not moving, while the flow pressure is the pressure exerted by the fluid in motion. By measuring and comparing these pressures before and after a change in the system, scientists can analyze the effects of the change on the fluid behavior.
