Engineering Thermodynamics Otto cycle efficiency is higher than Diesel cycle efficiency for the same compression ratio and heat input because in Otto cycle Heat rejection is lower Expansion and compression are isentropic Maximum temperature is higher Combustion is at constant volume Heat rejection is lower Expansion and compression are isentropic Maximum temperature is higher Combustion is at constant volume ANSWER DOWNLOAD EXAMIANS APP
Engineering Thermodynamics The distillation carried out in such a way that the liquid with the lowest boiling point is first evaporated and re-condensed, then the liquid with the next higher boiling point is then evaporated and re-condensed, and so on until all the available liquid fuels are separately recovered in the sequence of their boiling points. Such a process is called Carbonisation Cracking Full distillation Fractional distillation Carbonisation Cracking Full distillation Fractional distillation ANSWER DOWNLOAD EXAMIANS APP
