Document Summary
Nth = 1- qout/qin = function of r = v1/v2 assume stationary air standard, approximate analysis fixed mass of air piston cylinder - closed qin - 2-3 e3-e2= qin closed system. Qin = q23 = u3-u2 dvide by mass q23 = u3-u2 divide by mass q23 = u3 -u2 = qout = 4-1. T1/t2 = (v2/b1) ^(k-1) = (v3/v4) ^ (k-1) = t4/t3. An ideal otto cycle with a compressio ratio of 8 begins with air at 100kpa and 17c before compression. 800 kjkg of heat is added during isochoricheating. using exact analysis determine: max t and p in the cycle, bet work per kg, nth, mean-effective-pressure r = v1/v2 =v4/v3 = 8. Assume stationary air standard, closed exact analysis nth =/ 1- 1/(r^(k-1)) 1, tmax = t3 and pmax = p# look at 1 -2 -3. 1-2 isentropic compression on an ideal gas with exact analysis. Pv= rtin a -17 i know that vr1 = 676. 1 at 290k.
