The scientists working on Mars rover want to know what is the heat transfer from the solar panels of the rover on the surface of Mars. Consider the panels can be approximated as flat plate. The scientists performed a test in a wind-tunnel on Earth where they maintained the same Reynolds number as is expected on Mars. Previous data suggests that the Prandtl number of the air on Mars is approximately 70% of that of the gas used in the wind tunnel (Pr=1). If they measured the Nusselt number in the wind tunnel be 234, what will the Nusselt number be on Mars? 2077
