A thermodynamic cycle with 0.1 kg of air has 3 processes as in the figure. Assume air as ideal gas. Consider constant specific heat approach (take the air properties at 300 K). P;=140 kPa, Pz=420 kPa and V, = 0.05 m². PA 1-2: Constant volume process 2 2-3: Polytropic process with n=1 3-1: Constant pressure process 3 a) Find the temperature at State 3, in K. b) Calculate the specific work in the Processes 2-3 and 3-1, in kJ/kg. c) Calculate the heat transfer per unit mass in the Processes 2-3 and 3-1, in kJ/kg.

Finding mas flow rate, in lb/s, and exit temperature in F. Step by step solution please thank youuu

A piston/cylinder arrangement initially contains air at 150 kPa, 400°C. The setup is allowed to cool to the ambient temperature of 20°C. a. Is the piston resting on the stops in the final state? What is the final pressure in the cylinder? b. What is the specific work done by the air during this process?
