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 determine the area given pressure and velocity, you can use the equation for mass flow rate. The mass flow rate is equal to the product of density, velocity, and area. By rearranging this equation, you can solve for area as mass flow rate divided by (density × velocity).

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.


How come Bernoullis principle say that as pressure decreases velocity increases when we know that as area increases pressure decreases we also know that as area decreases velocity increase?

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.


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


If you increase force keeping the area the same what happens to pressure?

if force increaces and area stays the same then pressure


How do you find the mass of an object when the pressure and area is given?

Mass = Pressure*Area


How do you find pressure when given mass and area?

Pressure=mass/unit 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 do you find pressure given force and area?

P = F/A, so Area = Force/Pressure


Will anyone answer you what is the force that air exerts on a given area?

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.


Find position given velocity vs time graph?

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.
