Question

VTf/2 = constant. (1.39) VP = constant, (1.40) 8. Use equations (1.39) and (1.40) on p. 26 in the textbook to derive the following expression for adiabatic expansion of an ideal gas. (Hint: use the relation d(alnx) = a dx/x.) $\frac{dT}{dP} = \frac{2}{f+2} \frac{T}{P}$ Combine this relation with the barometric equation to calculate the dry adiabatic lapse rate, dT/dz, for earth's troposphere in units of K/km.

          VTf/2 = constant.

Use equations (1.39) and (1.40) on p. 26 in the textbook to derive the following expression for adiabatic expansion of an ideal gas. (Hint: use the relation d(aln x) = a dx/x.) (dT)/(dP) = (2)/(f+2)(T)/(P) Combine this relation with the barometric equation to calculate the dry adiabatic lapse rate, d(T)/(d)z, for Earth's troposphere in units of (K)/(km). (Note you are not solving for anything, but just trying to derive the equation) VTf/2 = constant. (1.39) VP = constant, (1.40)
