Nusselt number for all value of GrPr and constant wall temperature Solution

Follow our step by step solution on how to calculate Nusselt number for all value of GrPr and constant wall temperature?

FIRST Step Consider the formula

Nu = {(0.825 + (\frac{0.387 \cdot ({(G \cdot Pr)}^{0.167})}{{(1 + {(\frac{0.492}{Pr})}^{0.5625})}^{0.296}}))}^{2}

Next Step Substitute values of Variables

∴

Nu = {(0.825 + (\frac{0.387 \cdot ({(0.5 \cdot 0.7)}^{0.167})}{{(1 + {(\frac{0.492}{0.7})}^{0.5625})}^{0.296}}))}^{2}

Next Step Prepare to Evaluate

∴

Nu = {(0.825 + (\frac{0.387 \cdot ({(0.5 \cdot 0.7)}^{0.167})}{{(1 + {(\frac{0.492}{0.7})}^{0.5625})}^{0.296}}))}^{2}

Next Step Evaluate

∴

Nu = 1.20342792990751

LAST Step Rounding Answer

∴

Nu = 1.2034
