The advancement of technology has led to the demand for hydrophobic surface coating and miniature components. However, recent studies only reveal the effects of superhydrophobic surface on Non-Newtonian fluid for circular channel. Hence, there is a need for further the understanding of another type of channel (i.e, plane channel). This study presents a numerical investigation on the hydrodynamic entrance length and thermal entrance length of power-law fluid for planar channel flow consists of alternating superhydrophobic grooves and ribs arranged parallel to the flow direction. The simulations were performed in low Reynolds number range 0.001<Re<100, for power-law index in the range of 0.5<n<1.5 with dimensionless gas area fraction in the range of 0.125<
