Unformatted text preview: Repeat Problem 14.45 using liquid methanol as the fuel instead of ethanol.” 3. Problem 14.55, page 607. Fundamentals of Thermodynamics, Sonntag, et al., 6 th edition: Liquid pentane is burned with dry air, and the products are measured on a dry basis as 10.1% CO 2 , 0.2% CO, 5.9% O 2 , remainder N 2 . Find the enthalpy of formation for the fuel and the actual equivalence ratio. 4. Problem 14.49, page 606. Fundamentals of Thermodynamics, Sonntag, et al., 6 th edition: In a new high-efficiency furnace, natural gas, assumed to be 90% methane and 10% ethane (by volume) and 110% theoretical air each enter at 25 °C, 100 kPa, and the products (assumed to be 100% gaseous) exit the furnace at 40 °C, 100 kPa. Compare this to an older furnace where the products exit at 250 °C, 100 kPa....
