Consider a Carnot heat engine operating with steam as the working uid, among reservoirs atTL = 200C and TH = 500C.
Do the following, using the steam tables:
1) Draw the cycle on a PV diagram. Label the state points 1, 2, 3, 4 starting with the low-pressure, low-temperature state.
2) Let the lowest pressure in the cycle (P1) be 1 bar, and the highest (P3) be 80 bar. Find the values of P2 and P4.
3) Compute the heat Q and work W on each leg of the cycle; tabulate your results (SI units).
4) Compute the eciency of this cycle as a heat engine. Compare to the ideal-gas result for the Carnot eciency, and briey comment on the comparison.
Ammonia is oxidized with air to form nitric oxide in the first step to produce nitric acid. The reaction occurs in a well insulated continuous reactor based on the stoichiometry:
