Thermal efficiency and compression ratio:
Calculate thermal efficiency and compression ratio for automobile working on otto cycle. If energy generated per cycle is thrice which of rejected during the exhaust. Consider fluid as an ideal gas with = 1.4
Sol.: Since we have
Where
Wotto = (Q1 - Q2)/Q1
Q1 = Heat supplied
Q2 = Heat rejected
Given that Q1 = 3Q2
otto = (3Q2 - Q2)/3Q2 = 2/3 = 66.6% ...(i)
We also have;
Qotto = 1 - 1/(r) - 1
0.667 = 1/(r)1.4 - 1
r = (3)1/0.4 = 15.59
