FORMULA SHELF 1 of 370

The arithmetic behind the work: what to measure, what to type in, and what the answer comes out as. Every formula says what the symbols mean and gives a worked example, so you can check it against a job you have already done.

Quick calculators. A calculator appears where the formula is a single, clean equation with clear symbols. It is a convenience, not an authority: double-check every result yourself, especially doses, loads, torque and safety-critical settings.

Ideal gas law

P x V = n x R x T

SYMBOLS · P = pressure (Pa); V = volume (m3); n = moles; R = 8.314 J/mol K; T = temperature (K)

UNITS · Pa m3

HOW TO USE

The rule behind a pressure cooker, a tyre, a gas cylinder and a fermenting barrel. Pressure rises with temperature and with the amount of gas, and falls as the volume grows.

EXAMPLE

A 20 L bottle at 20 C and 2 bar holds roughly 0.8 moles.
