Engineering Thermodynamics Which of the following is the correct statement of the second law of thermodynamics? All of these It is impossible to transfer heat from a body at a lower temperature to a higher temperature, without the aid of an external source 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 All of these It is impossible to transfer heat from a body at a lower temperature to a higher temperature, without the aid of an external source 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 ANSWER DOWNLOAD EXAMIANS APP
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 Maximum temperature is higher Expansion and compression are isentropic Combustion is at constant volume Heat rejection is lower Maximum temperature is higher Expansion and compression are isentropic Combustion is at constant volume ANSWER DOWNLOAD EXAMIANS APP
Engineering Thermodynamics For a perfect gas, according to Boyle’s law (where P = Absolute pressure, V = Volume and T = Absolute temperature) P v = constant, if T is kept constant T/P = constant, if v is kept constant V/T = constant, if p is kept constant P/T = constant, if v is kept constant P v = constant, if T is kept constant T/P = constant, if v is kept constant V/T = constant, if p is kept constant P/T = constant, if v is kept constant ANSWER DOWNLOAD EXAMIANS APP
