Unformatted text preview: m (reversible) process. How can we evaluate this integral? We look at three examples: - P may be constant (see Example 4-2). - P may be defined by ideal gas law for an isothermal process (see Example 4-3). - Process may be polytropic (Section 4-1). Lesson 4, Geof Silcox, Chemical Engineering, University of Utah II. Energy and the First Law of Thermodynamics 3. Evaluation of integral. Example - Air is contained in a pistoncylinder device at 500 kPa at an initial volume of 0.040 m3. The air expands to...
