Velocity is not involved in the definition of pressure,
so knowing it doesn't help you calculate pressure.
Pressure = force/area
You may be talking about wind pressure, which obviously does depend on the
speed of the wind, or on the speed of the object through quiet air. In order to
know the wind force, you have to know the specific size, shape, dimensions, and
surface texture of the object past which the air is moving.

How do you find area if force and pressure given?
To find area, you can use the formula: pressure = force/area. Rearrange the formula to solve for area: area = force/pressure. Plug in the given force and pressure values to calculate the area.
What is the formula of thrust?
The formula for thrust is given by: Thrust = mass flow rate x exit velocity + (exit pressure - ambient pressure) x exit area
How fast does air with a velocity pressure of 0.20 in w.g. move through a round duct?
The velocity of air flowing through a round duct can be calculated using the formula: Velocity = (2 * velocity pressure) / (air density). Given the velocity pressure of 0.20 in w.g., the air density needs to be known to determine the velocity.
How do you get cfm with a manometer?
To calculate CFM (cubic feet per minute) using a manometer, measure the pressure difference across a restriction in the airflow system. Use the manometer reading and the area of the restriction to determine the velocity pressure. Then, use the velocity pressure to calculate the airflow in CFM using the formula CFM = (Velocity Pressure * Area of the Restriction) / 4005.
How can one determine velocity from an acceleration-time graph?
To determine velocity from an acceleration-time graph, you can find the area under the curve of the graph. This area represents the change in velocity over time. By calculating this area, you can determine the velocity at any given point on the graph.
