Fluid Mechanics and Thermal Sciences Question on Thermodynamic systems and processes
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)
Answer
The correct answer is:58.0 to 61.0
