The Clausius-Clapeyron equation is represented as lnP = A - C/T, where A and C are constants that vary based on the material and specific conditions such as temperature and pressure. For water, steam tables provide the necessary values for A and C, allowing for interpolation of pressure data at specific temperatures. This equation demonstrates a linear relationship between lnP and 1/T, which can be utilized for accurate predictions within defined temperature ranges.
PREREQUISITESChemists, physicists, and engineers involved in thermodynamics, particularly those studying phase transitions and vapor pressure relationships.
They depend on the material under consideration, and on conditions like temperture and pressure. For water you could look at some steam tables. What the equation says is that log P and 1/T are linear as a 1st approximation. The equation can be used to interpolate a data set. Ie you know P(T) for water in 5 K increments from 273 to 373 and want to know P(300.62).connard said:Hi everyone!
I'm searching for the constants in Clausius-Clapeyron equation
lnP=A-C/T
I'ld like to know the value of A and C. (for Pressure unity is hPa and Temperature is K )
Thanks
