            Problem 5—Estimation of Heating Value of Natural Gas
            Calculate the net heat content for the gas given in Problem 1.
            Solution of Problem 5
            Following the equations for calculating the heating value of the gas from its
            composition, we obtain the following results:
                                  L c;ideal 5 1080:7BTU=scf
                                       z 5 0:9973

                                    L c 5 1084BUT=scf

               The details of the calculations are given in Table 3.20.
