4) The work produced by a piston-cylinder device depends on the pressure inside the cylinder and the amount the piston moves, resulting in a change in volume inside the cylinder. Mathematically In order to integrate this equation, we need to understand how the pressure changes with the volume. We can model most combustion gases as air and assume that they follow the ideal gas law PV- nRT where P- pressure, kPa, volume, m n- number of...

Air goes through a polytropic process in a piston/cylinder setup. The polytropic index is n. The process starts at P1 kPa, T1 oC, and ends with a pressure of P2 kPa. Answer Questions 6-8 about this process, considering the given information in Question 6. Assume air to be an ideal gas. Let, n=1.5 P1=2.3 MPa T1= 8.9 ×102 °C P2=2.1 ×102 kPa Cp = 1.004 kJ/kg-K, Cv = 0.717 kJ/kg-K, R = 0.287 kJ/kg-K Find the final temperature, in oC...

Air is trapped in a piston cylinder arrangement. The air expands from a temperature of 60 C and a pressure of 280 KPa to a pressure of 140 KPa. During the process, 30 KJ/Kg of work is done and 14 KJ/Kg of heat is removed. The initial volume is 0.00878 m^3. a) What is the mass of the air? b) What is the temperature change during this process? c) What is the entropy change during this process? d) Does the...

Constant Pressure Process Oxygen (molar mass 32 kg/kmol) expands reversibly in a cylinder behind a piston at a constant pressure of 3 bar. The volume initially is o.o1 m2 and finally is o.o3 m3, the initial temperature is 17 C. Calculate the work output and the heat supplied during the expansion. Assume Oxygen to be a perfect gas and take Cp o.g17 kJ/kgK. 2.

A horizontal piston/cylinder arrangement is placed in a constant temperature bath. The piston slides in the cylinder with negligible friction, and an external force hold it in place against an initial gas pressure of 1 bar. The initial gas volume is 0.04 m^3. The external force on the piston is reduced gradually, and the gas expands isothermally as its volume triples. (a) If the volume of the gas is related to its pressure so that the product PV^t is constant,...

A horizontal piston/cylinder arrangement is placed in a constant-T bath. The piston slides in the cylinder with negligible friction, and an external force holds it in place against an initial gas pressure of 16 bar. The initial gas volume is 0.04 m^3. The external force on the piston is reduced gradually, and the gas expands isothermally as its volume doubles. If the volume of the gas is related to its pressure so that the product PV^t is constant, what is...
