7. Consider the diagram below. A 10 kg piston has a diameter of 50 cm. At initial condition it is loaded by a linear spring with spring constant of 100 kN/m. Also, assume an atmospheric pressure of 90 kPa acts on the piston. Air in the cylinder has initial volume of 0.1 m', initial absolute pressure of 200 kPa, and initial temperature of 30 C. The cylinder is connected to a 300 kPa (absolute) air supply line, and the connection valve is opened until the pressure equilibrium arrives. Calculate the final pressure and final volume of air in the cylinder. Patm = 90 kPa 300 kPa Ari Supply line 7. Consider the diagram below. A 10 kg piston has a diameter of 50 cm.
