.12 A 280-mm diameter cylinder fitted with a frictionless leakproof piston contains -02 kg of steam at a pressure of 600 x 10³ N/m² and a temperature of 200 °C. As the piston moves slowly outwards through a distance of 305 mm, the steam undergoes a fully- resisted expansion during which the steam pressure p and the steam volume Vare related by pV* = constant, where n is a constant. The final pressure of the steam is 120 x 10° N/m². Determine: (a) the value of n (b) the work done by the steam e) the magnitude and sign of the heat transfer. .12 A 280-mm diameter cylinder fitted with a frictionless leakproof piston contains -02 kg of steam at a pressure of 600 x 10³ N/m² and a temperature of 200 °C.
