WebOct 7, 2016 · Nusselt number tells the heat transfer. Rayleigh number tells you the free convection flow condition (velocity, density etc.). We know the stronger the flow, the more heat exchange can likely be involved. It might not be linear and might not be even in power formula.We do this test to establish this relationship. optomate help
