| The following code and image shows that the FrameStyle directive of a LogPlot does not show correctly when exported to SVG (tickmarks on vertical axis are missing), but does show properly for JPG. Plot shows correctly when exported SVG and JPG.... |
| It appears that ThermodynamicData has the incorrect reference state for carbon dioxide. [Span and Wagner (1996)][1] define the reference state of CO2 for which entropy and enthalpy are zero to have pressure 0.101325 MPa and temperature 298.15 K... |
| This function calculates the entropy of saturated vapor by taking the limit as the pressure approaches the saturation pressure from below. However, `sSatVapor[0.85]` returns Limit[obj$3516393[m], m -> 1, Direction -> 1]. Thanks. ... |
| This function is supposed to return the pressure corresponding to an entropy (s) and temperature (t). Instead the function just returns the initial guess in FindRoot. What's wrong? Thanks. pressure[s_Real, t_Real] := ... |
| Ok. Why doesn't the background of the framed legend hide the gridlines? I'm running version 11.1.1.0. Thanks. ContourPlot[{y^2 == 2 x, x == Sqrt[\[Pi]] y/2 Exp[y^2/4] Erf[y/2]}, {x, 0, 20}, {y, 0, 3}, GridLines -> All, ... |
| I want to use standard engineering notation, so I use Symbolize[] to define a symbol q'' (q double prime) for the heat flux (heat transfer rate per unit area) as a composite of the letter q and double prime (actually two aliased single quotes:... |
