Engineering Thermodynamics The polytropic index (n) is given by log (v1/ v2)/ log (p1/p2) log (p1p2)/log (v1v2) log [(p1v1)/(p2v2)] log (p2/ p1)/log (v1/ v2) log (v1/ v2)/ log (p1/p2) log (p1p2)/log (v1v2) log [(p1v1)/(p2v2)] log (p2/ p1)/log (v1/ v2) 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
Engineering Thermodynamics Which of the following is the correct statement of the second law of thermodynamics? It is impossible to construct an engine working on a cyclic process, whose sole purpose is to convert heat energy into work It is impossible to transfer heat from a body at a lower temperature to a higher temperature, without the aid of an external source All of these There is a definite amount of mechanical energy, which can be obtained from a given quantity of heat energy It is impossible to construct an engine working on a cyclic process, whose sole purpose is to convert heat energy into work It is impossible to transfer heat from a body at a lower temperature to a higher temperature, without the aid of an external source All of these There is a definite amount of mechanical energy, which can be obtained from a given quantity of heat energy ANSWER DOWNLOAD EXAMIANS APP
