Show that the air standard efficiency for Ericsson cycle is given by -T) In(r,)() Тн 1+ In(rp)( (ТH - TL where TH and T, are the maximum and minimum temperatures of the cycle, and is the pressure Гр ratio. Hint: No Regenerator is used here. Show that the air standard efficiency for Starling cycle without regenerator is given by (-1)+-1) n(r) (T-1)1)n(r) n=1 - where r is the compression ratio and is the maximum and minimum temperature ratio. (рн — PLr)(1 — -D Show that the mean effective pressure (mep) pm for the Otto cycle is given by pm = (-1)(r - 1) Net Work output Swept Volume where pH max, PL = Pmin and r = compression ratio (CR). Hint: pm
