The total force vector acting at the center of pressure is the surface integral of the pressure vector field across the surface of the body. The resultant force and center of pressure location produce an equivalent force and moment on the body as the original pressure field. Pressure fields occur in both static and dynamic fluid mechanics ...
Formula Result of #3 minus #2: Difference between #3 and #1: Sum of #1 and #2 Description What is typically understood as "pressure"; not influenced by velocity. Potential for pressure rise in fluid due to kinetic energy. Static pressure of fluid if all kinetic energy were converted into pressure.
HCOP = ∫px x dx / ∫px dx, where px is the pressure at x distance from the bottom With this formula we see the height of the COP for a plane surface is H/3 from the bottom, as shown in Figure 2 (left). With two fluids of differing density in a volume, the slope of the pressure prism will not be constant over the depth. See Figure 3 (right).

Many thermodynamic equations are expressed in terms of partial derivatives. For example, the expression for the heat capacity at constant pressure is: = which is the partial derivative of the enthalpy with respect to temperature while holding pressure constant.
In fluid dynamics, the pressure coefficient is a dimensionless number which describes the relative pressures throughout a flow field. The pressure coefficient is used in aerodynamics and hydrodynamics. Every point in a fluid flow field has its own unique pressure coefficient, C p.
At ambient pressure, P=0 GPA is known, so, the volume, pressure, and temperature are all given. Then, authors [9] predict the pressure value from the given (V, T) from pressure-dependent thermal expansion equation of state. The predicted pressures match with the known experimental value of 0 GPa, see in Figure 2.
