    Creating large amount of datum points

    Hi All, From a double curved surface of a step file I want to measure the position (XYZ) of points on this surface w.r.t. a coordinate system. Either it concerns a large pattern (600 x 600) so also a lot of points (360000). In this way the surface is defined by points which can be used in an...

    Dependence of pressure on viscosity of air

    Thanks for your quick respons. Actually I'm looking for the viscosity of air from 1 atm (1000 mBar = 15 psi) until vacuum (10^-6 mBar = 15*10^-8 psi). Probably the viscosity will be reduced strongly.
