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?
You can find Dynamic pressure by using bernoulli's equation. P = (density * velocity^2)/2
How do you find pressure if force and area is given?
force= pressure*area
Explain Why Nozzles are made convergent and Divergent?
According to Bernoulli's principle, pressure head, velocity head, and datum head are constant between two points. Additionally, continuity equation is area*volumetric flow rate is constant. So, in the convergent section, area is low which will result higher velocity and lower pressure. In the divergent section, area will increase, velocity will decrease, and consequently, pressure will increase.
How does strong wind occur?
Strong winds occur when there is a steep gradient in air pressure, i.e. if the difference in air pressure is large, the air moves from the area of higher pressure to the area of lower pressure at a considerable rate, or velocity.
Bernoullis principle about air velocity and pressure?
velocity and pressure have inverse relation. when velocity increases then pressure at that point decrease and vice versa.

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.
How do you find pressure if force and area is given?
force= pressure*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 do you find pressure given force and area?
P = F/A, so Area = Force/Pressure
