I need complete work to these answers.
7) a) P2 = 698.06 kPa, T2 = 342.10 K, V2 = .00652 m3 P3 = 320.59 kPa, T3 = 157.11 K, V3 = .00652 m3 P4 = 367.41 kPa, T4 = 165.70 K, V4 = .006 m3 b) Q2-3 = -3845.48 Joules c) Q4-1 = 4039.01 Joules d) W1 = 372.10 J, W2 = 0 J, W3 = -178.56 J, W4 = 0 J Wtotal = 193.53 Joules, Eff = 4.79% e) ?S1-2 = 0 J/K, ?S2-3 = -16.18 J/K, ?S3-4 = 0 J/K, ?S4-1 = 16.18 J/K, ?Stot = 0 J/K f) COPcooling mode = 19.87, COPheating mode = 20.87
T) The same gas in problem I5 is to undergo an Otto Cycle. It starts in a chamber of volume 05 m'J and temperature 36C! Kelvin and pressure SUD kF'a (state 1). During the Power Stroke, it is allowed to expand adiabatically to a volume of . 3 00552 m [state 2). Then heat i s extracted from the gas isovolumehically as the Exhaust valve is opened until its pressure drops to 3213.59 kPa [state 3). Then, during the Compression Stroke, it is compressed adiabcatically to its original volume (state 4). Finally it returns to its initial state isovolumehically as the Spark Plug ignites and adds heat to the gas. all What are the Pressure, Eblume, and Temperature in each state\"? bl How much heat is extracted from the system between states 2 and 3 ? c) How much heat is supplied to the system between states 4 and l? d) livi'hat is the work done by the gas in each stage and the total work and the ideal efciency of this engine? eII What is the change in entropy from state 1 to 2, 2 to 3, 3 to 4and 4to l and the total change in entropy? fjl If the process is run backwards, what is the GDP in the cooling mode and the heating modeStep by Step Solution
