Specific heat ratio k
WebThe specific heat ratio, (or ), is a function of only and is greater than unity. An ideal gas with specific heats independent of temperature, and , is referred to as a perfect gas. For example, monatomic gases and diatomic gases at ordinary temperatures are considered perfect gases. To make this distinction the terminology "a perfect gas with WebThe Specific heat ratio is the ratio of the heat capacity at constant pressure to heat capacity at constant volume and is represented as κ = Cp/Cv or Specific Heat Ratio Dynamic = Heat Capacity Constant Pressure/Heat Capacity Constant Volume.
