Pressure and Gauge Pressure Quiz

Pascal (Pa) = One newton per square metre (N/m2) Pound-force per square inch (psi) = Traditional unit of pressure in the imperial and US customary systems Atmosphere (atm) = Standard atmospheric pressure, equal to the pressure at sea level Torr = Defined as 1⁄760 of standard atmospheric pressure

Gauge pressure = Pressure relative to the ambient pressure Manometric units = Expressing pressures in terms of the height of a column of a particular fluid in a manometer IUPAC recommendation for pressure = Lower-case p as the symbol for pressure Upper-case P for pressure = Widely used symbol for pressure

Python = General-purpose programming JavaScript = Client-side scripting for web applications SQL = Database queries CSS = Styling web pages

<p>Newton (N) = Unit of force in the SI system Pound-force (lbf) = Force exerted by gravity on one pound of mass at standard gravity Dyne = Cgs unit of force equal to one gram centimetre per second squared (g·cm/s2) Kilogram-force (kgf) = Force exerted by one kilogram of mass in standard Earth gravity</p> Signup and view all the answers
