So, that will be Nusselt number equals to hL by kf and there will be a function of g rhol rhov, L cube by mu square, Cp delta T by and mu Cp by k which is Prandtl number L square by sigma.
तो, वह नुसेल्ट संख्या hL by kf  के बराबर होगी और g rhol rhov, का एक फंक्शन L cube by mu square, Cp delta T by and mu Cp by k होगा जो कि प्रांड्टल संख्या L square by sigma है।
