How to solve this thermodynamics question?
8 7 Preparatory exercises A p/105 Pa 8 - 1. Figure 1a shows a cyclic process consisting of two isochoric and two isobaric processes. The enclosed area in the pV- 74 diagram represents the net work performed in one cycle. 6- 5- a) What quantity does the product p.V measure? b) How much net work is done by the engine in one cycle? c) If the cycle was going counter-clockwise instead, what 3- V/10-3 m3 would the net work be then? d) What power is delivered from the engine if it takes Figure 1a. A pv-diagram of a cyclic 2 3 5 6 7 8 0,20 s for the process to make one turn? process consisting of two isochoric and Answer: b) 1.6 kJC) -1.6 kJ d) 8.0 kW two isobaric processes. 4- 4 3 2 H 4
