The piston diameters in Fig. P4-114 are D1 = 10 cm and D2 = 4 cm. Chamber 1 contains 1 kg of helium, chamber 2 is filled with condensing water vapor, and chamber 3 is evacuated. The entire assembly is placed in an environment whose temperature is 200°C. Determine the volume of chamber 1 when thermodynamic equilibrium has been established.
