A flue gas at 1.05 atm and 150 °C has an Orsat analysis of 60% CO2, 30% N2, and the balance O2. The vapor pressure of water in this flue gas is 20 mmHg. It flows through a 3 in diameter pipe at a speed of 25 m/s. a. Determine the wet basis composition of the flue gas.  b. Find the molar flow rate [kmol/h] of N2 in the flue gas. c. Find the average molar mass [g/mol] of the flue gas.  d. Calculate the mass flow rate [kg/h] of the flue gas.  Use the following molar masses [g/mol]: H: 1; C: 12; N: 14; O: 16
