how to find the corresponding value for L/h = 2.

Please show the process of finding

m/Ua h/a L/a

I tired by by linear interpolation but values ar inappropriate. what is the process?

\begin{tabular}{ccccc} m/(Ua) & h/a & L/a & L/h & umax/U \\ \hline 0.0 & 0.0 & 1.0 & & 1.0 \\ 0.01 & 0.031 & 1.010 & 32.79 & 1.020 \\ 0.1 & 0.263 & 1.095 & 4.169 & 1.187 \\ 1.0 & 1.307 & 1.732 & 1.326 & 1.739 \\ 10.0 & 4.435 & 4.583 & 1.033 & 1.968 \\ 100.0 & 14.130 & 14.177 & 1.003 & 1.997 \\ & & & 1.000 & 2.000 \\ \hline \end{tabular}
