Equation for Surface Pressure?

In summary, the equation for surface pressure is P = F/A, where P is the force applied, F is the force applied, and A is the area over which the force is applied. Surface pressure is different from atmospheric pressure in that it is measured in units of force per unit area and is used in various engineering and scientific applications. Surface pressure can be affected by factors such as the force applied, the area over which the force is applied, and the atmospheric conditions. It is typically measured using instruments such as pressure gauges and is expressed in units of force per unit area, such as psi or Pa.

Hi guys, so I have a problem where I am given the stagnation point pressure and the free stream velocity as well as the temperature of the isothermal plate and temperature of the free stream.


I am asked to plot the surface pressure at the isothermal plate for a range of x=0 to x=1 given that I have a free stream velocity of 5*x

Can someone help me, I'm not sure what the equation is for surface pressure.

Thanks!

FAQ: Equation for Surface Pressure?

What is the equation for surface pressure?

The equation for surface pressure is P = F/A, where P is surface pressure, F is the force applied, and A is the area over which the force is applied.

How is surface pressure different from atmospheric pressure?

Surface pressure is the force exerted on a surface per unit area, while atmospheric pressure is the weight of the atmosphere pushing down on a surface. Surface pressure is typically measured in units of force per unit area, such as pounds per square inch (psi) or pascals (Pa), while atmospheric pressure is measured in units of force per unit area, such as pounds per square inch (psi) or pascals (Pa), while atmospheric pressure is measured in units of force per unit area, such as pounds per square inch (psi) or pascals (Pa), while atmospheric pressure is measured in units of force per unit area, such as pounds per square inch (psi) or pascals (Pa).

How is the equation for surface pressure used in real-world applications?

The equation for surface pressure is used in various engineering and scientific applications, such as calculating the force exerted by a fluid on a surface, determining the load capacity of a structure, and studying the behavior of gases in different environments. It is also used in meteorology to study air pressure and its effects on weather patterns.

What factors can affect surface pressure?

Surface pressure is influenced by several factors, including the force applied, the area over which the force is applied, the material properties of the surface, and the atmospheric conditions. Additionally, the shape and orientation of the surface can also affect the distribution of surface pressure.

How is surface pressure measured and expressed?

Surface pressure can be measured using instruments such as pressure gauges, manometers, and pressure transducers. It is typically expressed in units of force per unit area, such as psi or Pa, but can also be represented in other units such as bars, atmospheres, or inches of mercury. It is important to specify the units when expressing surface pressure to ensure accuracy and consistency in measurements.
