The top of the burner is exposed to room conditions (Tsur,t = Too,t = 20°C, ht = 40 W/m2 · K), while the bottom of the burner is exposed to combus to ensure adequate airflow passage through the array. Recommend a design that enhances chip cooling.
Air enters a non-ideal gas turbine at T1 = 2290°F, P1 = 196 psia and exits at T2 = 1200°F, P2 = 14 psia. (a) Assuming constant specific heats evaluated at 1000F, find the turbine efficiency using the Air Tables.
For each case, determine the specific volume at the indicated state. Locate the state on a sketch of the T-v diagram.
