The entropy production or for nitrogen, an ideal gas, is 0.360 kJ/kg K when it is throttled from an initial pressure of 400 kPa. Determine (a) the final pressure, in kilopascals, to which the gas is throttled and (b) the ratio of the inlet to outlet area if the inlet and exit velocities are identical
