2. Gaseous nitrogen actuates a Carnot power cycle in which the respective volumes at the four comers of the cycle, starting at the beginning of the isothermal expansion, are Vi-10.10 L, V 14.53 L, V3-226.54 L, V 157.73 L. The cycle receives 21.1 kJ of heat. Determine (a) the work and (b) the mean effective pressure Ans. (a) 14.05 kJ: (b) 64.91 kPa 2.
