hydrostatic pressure
P= hdg
where;
p= pressure (N/m2 or Pa)
h=height (m)
d= density (kg/m3)
g= acceleration due to gravity
(9.81 m/s2)
e.g.
example problem.
a pressure gage register 40 psig in a region where the barrometer is 14.5 psia. fine the absolute pressure in psia., and kPa(KN/m2)
give.
Pg= 40 psia
Po= 14.5 + 40
p=54.5
b. P=54.5psia
=54.5 lb.....6894.8 N/m2
In2 1 psi
=37576606 N/m2
375.77 KN
p= 375.77 KPa
Pressure = Force/Area.
Pressure = force / area
the formula for pressure is:Mathematically:P= F/A or P= dFn/ dAwhere:p is the pressure,F is the normal force,A is the area of the surface area on contactScientifically:p= F/A
You might use the definition of pressure: pressure = force / area.
Pressure =Force/Area
my question is what is the formula for pressure?
There is not a formula for this, but you can use the formula for pressure. Then it can be put into the formula with temperature that you have.
The formula for pressure is: pressure= force divided by area The unit for pressure is: pascals (p) Enjoy:)

formula for force is pressure / area.
Pressure = (Force/Area)
Force over Area= Pressure
Pressure =Force/Area
but i think the absolute pressure is P(pressure)/{p(density)*g(gravity)}
