Discuss, with the aid of diagrams, the principles of operation of gas turbine plants. For an application for a Mechanical Engineering Internship Programme, a Mechanical Engineer mustexamine the operation of practical steam and gas turbines plants. The most efficient cycle is the Carnotcycle for given temperatures of source and sink. This applies to both gases and vapours. However, theRankine cycle is more suitable as a criterion for actual steam cycles than the Carnot cycle. In the application:

Consider a cold air-standard Diesel cycle. Operating data at principal states in the cycle are given in the table below. The states are numbered as in Fig. 9.5 with p1 = 100 kPa, T1 = 340 K, and T3 = 4850.3 K, r = 12 and rc = 2. For n = 1.3, cv = 0.718 kJ/(kg-K), and cp = 1.005 kJ/(kg-K), determine T2 in K.

(d) Why would it be desirable to operate automobile engines on a two-stroke cycle?
Projects 2: Rankine and Carnot cycle in practice Your colleague at the power plant station initiated a mutual discussion, where he suggested applying the Carnot cycle since it is considered the optimal cycle that steam power plant may be operated on. You were in a position to justify him why there many difficulties and impracticalities associated with the Carnot cycle in terms of the steam power plant, deliver a brief report explain why the Rankine cycle is preferred over the Carnot cycle in steam production plants, mention all impracticalities associated with applying Carnot cycle including the limitation of boiler and condenser temperature and pressure with respect to the surrounding saturation conditions (you may construct TS diagrams for both cycles to demonstrate your comparison).
