- i-Use the first law of thermodynamics to determine an algebraic equation for the combustorexit temperature (T 04 ) in terms of equivalence ratio (phi) if the fuel in Problem 2 is used. Hint:find the equation for f in terms of T04 and T03 in the canvas handout, our class notes, or in thetextbook in Chpt 5. Then solve that equation for T04 .Assume that the compressor exit temperature T 03 is 650 K. The heating value (Q R ) of thenew fuel in problem 2 is 39,000 kJ/kg fuel. The effective heat capacity cp of the mixture is constant and is 1.2 kJ/(kg-K). Insert these values into your equation for (T 04 ) in terms ofequivalence ratio (phi) ii-Now consider values of fuel-air equivalence ratios (phi) of 0.1, 0.2, 0.3, 0.4, 0.5. Use Matlab,Excel or some other program to use your equation from problem 2 to plot a graph of T04versus f.
