NUMERICAL 1 . An ideal air standard Otto cycle has a compression ratio of 8.5. If Y = 1 .4 then find efficiency? 8.5

NUMERICAL 2 . For an engine operating on air standard Otto Cycle the clearance volume is 10% --. Take Y = 1-4 of swept volume. Then the efficiency is O.1 14-1

NUMERICAL 3 . In an engine working on Ideal Otto Cycle the compression ratio is 5.5. The work output/cycle is 23.625 x 10 5 Vc Joule where Vc Clearance Volume in m3. Find M.E.P in bar. 4.5 m. e.p. =5.25 bar

NUMERICAL 4 . An engine working on air standard Otto cycle has a cylinder diameter of 10cm and stroke length of 15cm. If the clearance volume is 196.3 cm3 and heat supply = 1 800 kJ/kg, then find work output. 4 DL Vc = 0.5408 wnet= 973 kJ

i just want to ask a question
for a otto cycle at the 1/8th of stroke length pressure is 1.5 bar and at the stroke length of 7/8 pressure is 15 bar then to find efficiency of otto cycle taking gamma (Y) 1.4
