I need help to answer my problems on thermodynamics
3.) An ideal Diesel engine operates on fft3 cmearured at state 1) of air. Let p1=14.4 pria, t1=140∘C and let the cutoff be at 6.2% of the stroke. Find (a) t2,P2,v2,t3,V3,P4 and t4 by QA and QR c.) W and e, and (d) ρm 4.) An Otto cycle with a compression ratio of 7.5 operates from the suction conditions of 97.91kPaa,29.4∘C. Find the p and t at the end of comp (a) if cold air (k=1.4) is the working substance (b) if hot air (k=1.32) is the working vubstance (c) Solve for the ideal thermal efficiency based upon the condition given in (a) and (b).
