∴

h transfer = (\frac{0.023 \cdot ({13kg/s/m²}^{0.8}) \cdot ({10.18W/(m*K)}^{0.67}) \cdot ({1.5J/(kg*K)}^{0.33})}{({9.71m}^{0.2}) \cdot ({11N*s/m²}^{0.47})})

Next Step Convert Units

∴

h transfer = (\frac{0.023 \cdot ({13kg/s/m²}^{0.8}) \cdot ({10.18W/(m*K)}^{0.67}) \cdot ({1.5J/(kg*K)}^{0.33})}{({9.71m}^{0.2}) \cdot ({11Pa*s}^{0.47})})

Next Step Prepare to Evaluate

∴

h transfer = (\frac{0.023 \cdot (13^{0.8}) \cdot ({10.18}^{0.67}) \cdot ({1.5}^{0.33})}{({9.71}^{0.2}) \cdot (11^{0.47})})

Next Step Evaluate

∴

h transfer = 0.199198120596644W/m²*K

LAST Step Rounding Answer

∴

h transfer = 0.1992W/m²*K
