Unformatted text preview: EML 3100 Homework 1 Due Wednesday, January 18 From the Textbook : Problems 2.40, 2.47, 2.75, 2.82 Problem 5 : Hydrogen gas having an energy content per unit mass of e = 120 MJ/kg is stored in a tank at 200 bar and 25 C. The molecular weight of hydrogen is M = 2.016 g/gmol, and the corresponding gas constant is R = 4.124 J/g-K. The density of hydrogen is described by = , where the compressibility factor Z corrects for the deviation from ideal gas behavior that occurs at high pressure. At 200 bar and 25 C, Z is estimated as 1.130. Determine the product e in units of [MJ/m 3 ], which represents the energy content of the gas per unit volume. Problem 6 : The sketch below shows a curve in p- V coordinates defined by the polytropic equation = ? , where n and c are positive constants. Verify the following related results: = ln( 1 / 2 ) ln( 2 / 1 ) = ln( 2 / 1 ) ln( 1 / 2 ) , ? 2 1 = ln...
