Maximum number of lines in paschan back effect.

For the Otto cycle of air shown, P1= 1 bar, T1 = 290 K, V1 = 400
cm3. If T3 = 2200 K and compression ratio is 8, find (a) the heat addition, in kJ, (b) the net work, in kJ, (c) the thermal efficiency.
The mass of the air is 0.48 g.

3. A turbine has a power output of 7500 kJ/sec when steam with a mass flow rate of 11.11
kg/sec enters the turbine at 773 K, 8MPa and leaves as saturated vapor at 40 kPa. If the
surrounding of the turbine is at 25 °C, find the rate of entropy generation at steady state.

Potential temperature contain information on internal energy and geopotential energy

Validate that properties like enthalpy or specific heat of a mixture can be estimated from the composition of the mixture and property values for the consistent gases.

Validate that air has molecular weight of 28.97kg/(k mol).

A Carnot engine 'X' operates between temperature T(1) and T(2) And (T(1)>T(2)). A second Carnot engine 'Y' uses all the heat rejected by the engine 'X' and operates between temperature T(2) and T(3)
( where T(2)>T(3)). The efficiency of this combined X and Y together engine is?
ANS:1- {[T(2)+T(3)]/T(1)}
