- A piston-cylinder arrangement shown in the figure has a stop located 2m above the base. The cylinder initially contains air at 140kPa and 350°C and the piston is resting in equilibrium at a position which is 1m above the stops. The system is now cooled to the ambient temperature of 25°C. Consider air to be an ideal gas with a value of gas constant R = 0.287kJ/(kg.K).
The absolute value of specific work done during the process is _____kJ/kg (rounded off to 1 decimal place)

- At steady state, 500 kg/s of steam enters a turbine with specific enthalpy \(h_1 = 3500\ \text{kJ/kg}\) and entropy \(s_1 = 6.5\ \text{kJ . kg}^{-1}\text{K}^{-1}\). It expands reversibly in the turbine at 500 K. Exit properties: \(h_2 = 2500\ \text{kJ/kg}\), \(s_2 = 6.3\ \text{kJ . kg}^{-1}\text{K}^{-1}\). Find turbine work output (MW, integer).
