At this rate, Anand, you should teach a course as well! :)

Haha, you are already doing a great job! I should sit back and enjoy your course for now ;)
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
question selection is really good
sir plz two stroke and four stroke ki bhi video daal dijiye
can you come up with tutorials.may be after a week put a video on solutions

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

  4. 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

  5. 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

  6. 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
