ops in units and physical constants example



~~~

In the 2nd example the heat capacity ratio has been corrected to Cp/Cc


~~~

(%i121) sqrt(5/3*%R_gas/(4*gram/mol)*temp(27,C)); /* Helium sound velocity at 27 C, 
                                                     He(Cp/Cv)=5/3, 4gr/mol */

(%o121) (1019.719890214955*meter)/sec             /* pass */
