Impact Pressure - isentropic flow (ratio of specific heats =1.4)

In compressible fluid dynamics, impact pressure (dynamic pressure) is the difference between total pressure (also known as pitot pressure or stagnation ... more

Pressure dependence of the diffusion coefficient

Diffusivity or diffusion coefficient is a proportionality constant between the molar flux due to molecular diffusion and the gradient in the concentration ... more

Pulse pressure

The up and down fluctuation of the arterial pressure results from the pulsatile nature of the cardiac output, i.e. the heartbeat. The pulse pressure is ... more

Influence of the wind on a building

A building is a man-made structure with a roof and walls standing more or less permanently in one place. In general when the wind blows on a building then ... more

Dynamic Pressure - Compressible flow

In incompressible fluid dynamics dynamic pressure (indicated with q, or Q, and sometimes called velocity pressure) is the quantity defined as ... more

Mean arterial pressure

The mean arterial pressure (MAP) is the average over a cardiac cycle and is determined from measurements of the systolic pressure ... more

Load and Resistance Factor Design (LRFD) - Load combinations (eq1)

In structural engineering, a structure is a body or combination of pieces of rigid bodies in space to form a fitness system for supporting loads. ... more

Raoult's law

Raoult’s law is a law of thermodynamics and states that the partial vapor pressure of each component of an ideal mixture of liquids is equal to the ... more

Total Pressure to Static Pressure Ratio - in isentropic flow

In isentropic flow the ratio of total pressure to static pressure is given as shown
