The discussion revolves around a thermodynamics problem involving moist air ascending over a mountain range, specifically focusing on the application of the adiabatic equation in the context of air that is being heated by condensing vapor. Participants are examining the implications of this heating on the adiabatic process and the assumptions involved.
The discussion is active, with participants raising questions about the assumptions in the problem and the appropriateness of the methods used. Some have provided calculations and approximations, while others are seeking clarification on specific points. There is no explicit consensus, but productive dialogue is occurring regarding the underlying principles and calculations.
Participants are working within the constraints of a homework assignment, which may limit the depth of exploration into the problem. There are references to specific values and equations that are relevant to the calculations being discussed, as well as a focus on the conditions at specific points in the problem.
Very nice Jacob. Using the vapor pressure of ice at the final temperature, what do you now predict for the amount rained per kg?Jacob White said:So now after these corrections the final temperature I get is 270.89K which is about 0.6K higher than without considering ice. And that makes sense since we get some additional energy from freezing water.
It doesn't seem possible. What vapor pressure did you estimate at the final temperature?Jacob White said:Much more - about 3.737g.
That sounds right, but it implies 2.32 grams/kgJacob White said:0.5084 kPa
