Unformatted text preview: left ) = 286.16 kJ/kg. Thus, u(T) = 250.11 kJ/kg. Then from A-22, T = 350 K! To find pressure used the ideal gas law. This gives p = RT/v. By definition v = V/m where V = (V left + V right ). m is 20 kg, and the volumes V left and V right are found from the ideal gas law. V left = (m/2)RT left /p left and V right = (m/2)RT right /p right . Note that m/2 = 10 kg! Substitution gives for pressure bar p T p T R RT p right left 33 . 2 2 = + • =...
