Calculate the speed of sound (the sonic velocity) in gases, fluids or solids. A disturbance introduced in some point of a substance - solid or fluid - will propagate through the substance as a wave with a finite velocity.

Our pressure calculator uses the straightforward pressure formula below: p = F / A, where: p – Pressure; F – Force; and. A – Area of the surface. This pressure definition relates to the force applied perpendicularly to the object's surface.

The absolute pressure - p abs - is measured relative to the absolute zero pressure - the pressure that would occur at absolute vacuum. All calculations involving the gas law requires pressure (and temperature) to be in absolute units.
A gauge is often used to measure the pressure difference between a system and the surrounding atmosphere. This pressure is often called the gauge pressure and can be expressed as
Atmospheric pressure is the pressure in the surrounding air at - or "close" to - the surface of the earth. The atmospheric pressure varies with temperature and altitude above sea level. 1. Air density at altitude
Since 1 Pa is a small pressure unit the unit hectoPascal (hPa) is widely used, especially in meteorology. The unit kiloPascal (kPa) is commonly used in the design of technical applications - like HVAC systems, piping systems and similar. 1. 1 hectoPascal = 100 Pascal = 1 millibar 2. 1 kiloPascal = 1000 Pascal
First convert kilometres into metres. 1 km = 1,000 m. Next convert hours into seconds. 1 h = 3,600 s. Finally combine the two unit conversions. \ (340~\frac {\text {km}} {\text {h}} = \frac...
Dynamic pressure is the kinetic energy of a flowing fluid - liquid or gas - per unit volume - and can be expressed as. p d = 1/2 ρ v2(1) where. p d = dynamic pressure (N/m2(Pa), lbf /ft2(psf)) ρ = density of fluid (kg/m3, slugs /ft3 ) v = velocity (m/s, ft/s)
