Explanation Given: The temperature is 60 ° C . The specific pressure is 10 MPa . Concept used: Write the expression for pressure by Redlich-Kwong. P = R T v − b − ( a v 2 + c ⋅ b ⋅ v + d ⋅ b 2 ) …… (1) Here, p is pressure, R is universal gas constant, a, b, c, d are constants and v is specific volume. Write the expression for constant a. a = 0.42748 ⋅ ( 1 + f ⋅ ( 1 − ( T T c ) 1 2 ) ) ( R 2 T c P c ) …… (2) Here, T c is critical temperature, f is a constant and P c is critical pressure. Write the expression for constant f. f = 0.48 + 1.574 ( − ln ( P P c ) ln 10 − 1 ) − 0.176 ( − ln ( P P c ) ln 10 − 1 ) 2 …… (3) Write the expression for constant b. b = 0.08664 ⋅ ( R T c P c ) …… (4) Calculation: The critical constant carbon dioxide: T c = 304.1 K P c = 7.38 MPa The gas constant for carbon dioxide is 0.1889 kJ / kg ⋅ K . Substitute 10 MPa for P and 7.38 MPa for P c in equation (3) f = 0.48 + 1.574 ( − ln ( 10 7.38 ) ln 10 − 1 ) − 0.176 ( − ln ( 10 7.38 ) ln 10 − 1 ) 2 = − 1.52 Substitute 60 ° C for T, 304.1 K for T c , 0.1889 kJ / kg ⋅ K for R, − 1

Work and Heat Transfer

It is generally related to thermal engineering which tells about the use, creation, conversion and transfer of heat energy between the systems. It is also considered that to transfer heat from one source to another, transfer of masses is also required. T…
