#### Adiabatic Flame Temperature: ConcepTest and Example Problem

Try to answer this ConcepTest and solve this example problem before using this module. Studies show that trying to answer questions before studying material improves learning and retention. We suggest that you write down the reasons for your answers. By the end of this module, you should be able to answer these questions on your own. Answers will be given at the end of this module.

##### Example Problem 1

Calculate the adiabatic flame temperature when n-butane burns in 100% excess air at 1.0-bar pressure. Both air and n-butane gas are fed at 25°C. Use the heat capacities equation below (T is in kelvin) and the parameters in the table. These parameters are applicable from 273 to 1800 K.

\[C_{P,i} = A_i + B_iT + C_iT^2 + D_iT^3\]

gas | A_{i} | B | C | D |

H | 29.163 | 0.0145 | -2.02E-06 | 0.00E+00 |

O | 25.46 | 0.0152 | -7.15E-06 | 1.31E-09 |

N | 28.883 | -0.0016 | 8.08E-06 | -2.87E-09 |

CO | 22.243 | 0.0598 | -3.50E-05 | 7.46E-09 |
