An ideal Otto cycle has a compression ratio of 8. At the begin and 800 kJ/kg of heat is transferred to air during the constan specific heats at room temperature. The properties of air at r = 0.287 kJ/kg-K, and k=1.4. cermine the net work output. net work output is [ kJ/kg.

Q3: What is the ideal Otto-cycle efficiency for a 8:1 compression ratio, and how does it compare to the Carnot efficiency for a flame temperature of 3000K?

yale L 15 A gas power cycle uses air as the working fluid and has two turbine sections as shown in the figare below. The power produced by Turbine I is used to drive the compressor, and Turbine 2 produces output power W. Air enters the compressor with a semperature of 290 K and a mass flow rate of -2 (kgs] (State I); the air exits the compressor at 44SK (State 2). Heat is transferred from a high- temperature thermal reservoir, Ta- 1400 [K), to Heat Exchanger 1 at a rate Q,- The lemperature of the air is raised to 1100 [K] (State 3) as it flows through Heat Exchanger 1. The air enters Turbine I where it is expanded to State 4. The flow then proceeds to Turbine 2 and exits with a temperature of 500 (K] (State 5). Heat is then removed from the air through Heat Exchanger 2 at a rate Q which is rejectod to the low-temperature thermal reservoir, TL-200 (K). (A) Determine the temperature at the inlet to Turbine 2, Te (b) Calculate the power output from Turbine 2, W. (e) Calculate the rate of…
