The temperature in the vortex core is given by the equation above as T f = ( 80 000 101 325 ) 0.4 / 1.4 T i = 0.935 × 293.15 = 274 K , {\displaystyle T_{\text{f}}=\left({\frac {\scriptstyle 80\,000}{\scriptstyle 101\,325}}\right)^{\scriptscriptstyle 0.4/1.4}\,T_{\text{i}}=0.935\,\times \,293.15=274\;{\text{K}},} or 0.86 °C = 33.5 °F.
