A simplified relationship to estimate the higher-order contributions to viscosity of thermal plasmas has been reported. This relationship, depending only on the like interactions, is able to reproduce the exact contributions satisfactorily for hydrogen thermal plasmas with and without electronically excited states under local thermodynamic equilibrium conditions. At high pressures where the unlike interactions H-H{sup +} or H(n)-H{sup +} dominate over larger temperature range, it has been observed that these interactions do not play any significant role in estimating the higher-order contribution to viscosity of the thermal plasma.
