By comparing the equations for the thermal and hydrodynamic boundary layers, it can be shown that the ratio of 'xt' to 'x' is equal to the inverse of the Prandtl number raised to the power of one-third: xt/x = NPr^ (-1/3).
Therefore, the correct answer is option 'B', NPr^ (1/3).
Therefore, the correct answer is option 'B', NPr^ (1/3).
