Engineering Thermodynamics According to First law of thermodynamics, Total energy of a system remains constant Work-done by a system is equal to the heat transferred by the system Total internal energy of a system during a process remains constant Internal energy, enthalpy and entropy during a process remain constant Total energy of a system remains constant Work-done by a system is equal to the heat transferred by the system Total internal energy of a system during a process remains constant Internal energy, enthalpy and entropy during a process remain constant ANSWER DOWNLOAD EXAMIANS APP
Engineering Thermodynamics According to Avogadro's Hypothesis Gases have two values of specific heat Product of the gas constant and the molecular weight of an ideal gas is constant The molecular weights of all the perfect gases occupy the same volume under same conditions of pressure and temperature The sum of partial pressure of mixture of two gases is sum of the two Gases have two values of specific heat Product of the gas constant and the molecular weight of an ideal gas is constant The molecular weights of all the perfect gases occupy the same volume under same conditions of pressure and temperature The sum of partial pressure of mixture of two gases is sum of the two ANSWER DOWNLOAD EXAMIANS APP
Engineering Thermodynamics The efficiency of a gas turbine is given by (Actual temperature drop)/(Isentropic temperature drop) (Isentropic increase in temperature)/(Actual increase in temperature) (Net work output)/(Work-done by the turbine) (Net work output)/(Heat supplied) (Actual temperature drop)/(Isentropic temperature drop) (Isentropic increase in temperature)/(Actual increase in temperature) (Net work output)/(Work-done by the turbine) (Net work output)/(Heat supplied) ANSWER DOWNLOAD EXAMIANS APP
