You found that the variation is temperature in the troposphere is approximately linear. That agrees with ## T = ( T_o( 1- \alpha h ) ## (at least as a realistic model). Whether or not the slope is approximately correct in this problem you must compare it with a reputable source that states its value. In my fluids text book they state the temperature in the troposphere decreases linearly with increasing altitude at a lapse rate of ##5.87 \left[\frac{\text{K}}{ \text{km}}\right]##.Hak said:OK, but what pressure value should I enter? I don't think I understand...
As for ##P## you don't enter a value, you enter the relationship( i.e. the model that relates the variables ##P##, ##\rho## and ##T## )
