4.26 A cylinder of free volume 0.283 m is divided into two compartments by a piston. Initially the piston is at one end and the cylinder contains 1 kg steam at 423 K. Air from a supply main at 1400 kPa and 288 K is then admitted slowly via a throttle valve to the other side of the piston. Estimate the temperature of the air when pressure equilibrium is attained. Neglect any heat loss from the cylinder and assume no heat transfer across the piston. State clearly the assumptions made. Cy = 21 J/mol K for air. %3D
