Question

Find the pressure of saturated vapour as a function of temperature p (T) if at a temperature $$T_0$$ its pressure equals $$p_0$$.
Assume that: the specific latent heat of vaporization q is independent of T, the specific volume of liquid is negligible as compared to that of vapour, saturated vapour obeys the equation of state for an ideal gas. Investigate under what conditions these assumptions are permissible.

Q1
For water at 25oC,dps/dTs=0.189kPa/K (ps is the saturation pressure in kPa an Ts is the saturation temperature in K) and the specific volume of dry saturated vapour is 43.38m3/kg. Assume that the specific volume of liquid is negligible in comparison with that of vapour. Using the Clausius-Clapeyron equation, an estimate of the enthalpy of evaporation of water at 25oC (in kJ/kg) is
