Engineering Thermodynamics The expansion ratio (r) is the ratio of (where v1 = Volume at the beginning of expansion, and v2 = Volume at the end of expansion) v1/v2 (v1 + v2)/v2 (v1 + v2)/v1 v2/v1 v1/v2 (v1 + v2)/v2 (v1 + v2)/v1 v2/v1 ANSWER DOWNLOAD EXAMIANS APP
Engineering Thermodynamics The general gas energy equation is (where Q1 - 2 = Heat supplied, dU = Change in internal energy, and W1 - 2 = Work done in heat units) Q1 - 2 = dU × W1 - 2 Q1 - 2 = dU/W1 - 2 Q1 - 2 = dU + W1 - 2 Q1 - 2 = dU - W1 - 2 Q1 - 2 = dU × W1 - 2 Q1 - 2 = dU/W1 - 2 Q1 - 2 = dU + W1 - 2 Q1 - 2 = dU - W1 - 2 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 Cracking Fractional distillation Full distillation Carbonisation Cracking Fractional distillation Full distillation Carbonisation ANSWER DOWNLOAD EXAMIANS APP
