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.
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.
The formula for thrust is given by: Thrust = mass flow rate x exit velocity + (exit pressure - ambient pressure) x exit area
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.
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.
The force that air exerts on a given area is called air pressure. Air pressure is the result of the weight of the air above the given area pressing down on it. This pressure can vary depending on altitude, weather conditions, and temperature.
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.
By area do you mean cross sectional area of a stream tube? Bernoulli's principle only compares pressure and velocity and it covers all fluids. In the case of an ideal gas (constant density) decreasing the cross sectional area of a stream tube lets say; will not affect the pressure. But given any fluid volume..going from point a to point b if velocity decreases, particles in the fluid want to move outward. just remember any fluid must do two things move and apply pressure.
The formula for thrust is given by: Thrust = mass flow rate x exit velocity + (exit pressure - ambient pressure) x exit area
if force increaces and area stays the same then pressure
Mass = Pressure*Area
Pressure=mass/unit area
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.

P = F/A, so Area = Force/Pressure
The force that air exerts on a given area is called air pressure. Air pressure is the result of the weight of the air above the given area pressing down on it. This pressure can vary depending on altitude, weather conditions, and temperature.
To find the position from a velocity-vs-time graph, you need to calculate the area under the velocity curve. If the velocity is constant, the position can be found by multiplying the velocity by the time. If the velocity is changing, you need to calculate the area under the curve using calculus to determine the position.
Speed in a given direction is velocity.
