Homework Statement
Wind (dry air, so R=287 Jkg^-1K^-1) is moving isobarically along a flat surface at 30m/s. It hits a forest and 3/4 of its kinetic energy is transformed into heat energy by friction. What is the maximum temperature increase that could occur?
Homework Equations
The Attempt at a Solution
Using the potential temperature equation, theta = (1000/p)^(R/Csub p), and this equation: changeT = pot. temp. - initial temp., I get a change in temp. of -0.004T, which does nothing for me because there is no velocity included. I also tried using kinetic energy (1/2mv^2) to try to relate it to work and then internal energy, but I don't have a mass for the air parcel.
