Otto Cycle: Process, PV Diagram, Efficiency with Derivation & Applications

Otto Cycle: Process, PV Diagram, Efficiency with Derivation & Applications The Otto cycle was given by Dr. Nikolaus August Otto. It is a gas power cycle that is used in spark ignition engine (i.e. petrol engine) for its working. The entire modern petrol engine works on Otto cycle.  It consist of four processes, Two isentropic […]

The turbojet engine is another example of a Gas Turbine Engine. The working fluid is air or gas. Turbojet engine works on the principle of Newton’s third law of motion How? Let’s discuss in […]

Value of Ratio of Specific Heat Of Different Gases

Ratios of specific heat for gases in constant pressure and volume processes (Cp &Cv) Internal Energy For an ideal gas the internal energy (U) is a function of temperature. The internal energy of a thermodynamic system is the energy contained within it. A change in internal energy can be expressed as du = cv dT            […]

Ericsson engine is a closed cycle regenerative heat engine. It works on either air or any other gas. Ericsson cycle was invented by John Ericsson.Ericsson Cycle consists of two isothermal […]

STIRLING CYCLE WORKING, EFFICIENCY DERIVATION, P-V AND T-S DIAGRAM

Stirling cycle was devised by Stirling. It is a reversible cycle which consists of two isothermal processes and two constant volume processes. The last two processes are performed with the help of a refrigerator to make this cycle reversible. The p-v and t-s diagram of this cycle are shown in the figure. Let us now consider […]
