Formuli

Acoustics - Reverberation Time

Sabine Formula: RT60 = 0.16 x Room Volume / Absorption Area


Interstitial Condensation - Maximum Vapour Pressure

Antoine Equation: Log (Vapour Pressure) = A-B/(C+Temperature)

Re-arranged: Vapour Pressure = 10 ^ (A-B/(C+Temperature))

For Water = 10^(8.07131-1730.63/(233.426+Temperature))


Kinetic Energy: ½mv2

1 m3 of water weighs 1 tonne whereas 1 m3 of air weighs about 1.2 kg

Water moving at 3m/s through a 1m2 generator contains 13.5 kW of kinetic energy.

Air moving at 3m/s through a 1m2 generator contains 16.2 W
