An engineer is working with a gas initially at a pressure of 2 bar and a volume of 0.5m ^ 3 inside a piston cylinder device. The gas undergoes a two- step process inside the cylinder . The engineer needs to calculate the work of the overall process per kilogram of the gas. The processes are as follows: Process 1-2 Polytropic compression with n = 1.4 until the pressure reaches 4 bar. Process 2-3 Pressure remains constant while the volume reaches 0.4m ^ 3 Volume ( in m^ 3 ) at the end of the first step is (enter 3 digits after the decimal point )
