IAPWS Transport Properties IAPWS equations for the calculation of dynamic viscosity, thermal conductivity and surface tension of water and steam.
U in Heat Exchangers The determination of overall heat transfer coefficients U in heat exchangers is tedious and needs data not yet available in preliminary stages of the design. This article gives typical values of U for quick estimation of the required surface area. Cyclone Design Spreadsheet Free spreadsheet for cyclone separator design which allows calculation of dimensions, pressure drop, and efficiency as well as graphing of the efficiency against particle size.	Did You Know? Supercritical fluids don't liquefy. In fact, in the supercritical state it doesn't make sense to speak of gases and liquids because there's no difference. But what are supercritical fluids? Supercritical States
