At atmospheric pressure

## Engineering Thermodynamics The work ratio of a gas turbine plant is given by

(Actual temperature drop)/(Isentropic temperature drop)
(Net work output)/(Work-done by the turbine)
(Isentropic increase in temperature)/(Actual increase in temperature)
(Net work output)/(Heat supplied)

## Engineering Thermodynamics Universal gas constant is defined as equal to product of the molecular weight of the gas and

Gas constant
Specific heat at constant volume
Specific heat at constant pressure
Ratio of two specific heats

## Engineering Thermodynamics According to Avogadro’s law

The sum of partial pressure of the mixture of two gases is sum of the two
Equal volumes of all gases, at the same temperature and pressure, contain equal number of molecules
All of these
