Problem - 3 (20 points) Mechanical engineers, as well as most other engineers, use thermodynamics extensively in their work. The following polynomial can be used to relate the zero-pressure specific heat of dry air, cp [kj/(kg.K)], to temperature (K) : cp=0.99403+1.671104T+9.7215108T29.58381011T3+1.95201014T4 Determine the temperature that corresponds to a specific heat of 1.2kj/(kg.K). Use Bi-section method to solve the problem with an acceptable relative error of 1%. [Hint: Graphical method can be used to get an initial assumption of the upper and lower limit of the Bi-section method.]
