A frictionless piston-cylinder contains 0.1 kg of methane at 120 kPa and 40°C. The temperature is then increased to 150°C in an isobaric process. Determine the work and heat transfer during this process. Solution Find a) Boundary work b) Heat Q Data • Fluid: Methane State 1 : State 2 : a) Boundary work Equation To get the specific volumes, use the ideal gas equation or use NIST Solving for v So, c) Heat Q Equation Where • (there is NO other type of work except the boundary work) . So. Or From NIST Fluid Data Isobaric Data for P=0.12000 MPa Temperature Pressure Denalty Volume (c) (MP) (3) 012000 740 40.000 1.350 150.00 0120000543 1.4268 Thanafan Energy 71 343.52 LIKE 274220 901 12111
