STEP 1: Convert Input(s) to Base Unit

Convective Heat Transfer Coeff of Solar: 4.5 Watt per Square Meter per Kelvin --> 4.5 Watt per Square Meter per Kelvin No Conversion Required
Equivalent Radiative Heat Transfer Coefficient: 1.162423 Watt per Square Meter per Kelvin --> 1.162423 Watt per Square Meter per Kelvin No Conversion Required
Convective Heat Transfer Coeff of Solar Bottom: 3.2 Watt per Square Meter per Kelvin --> 3.2 Watt per Square Meter per Kelvin No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

h_e = h_fp+(h_r*h_fb)/(h_r+h_fb) --> 4.5+(1.162423*3.2)/(1.162423+3.2)

Evaluating ... ...

h_e = 5.35268063184153

STEP 3: Convert Result to Output's Unit

5.35268063184153 Watt per Square Meter per Kelvin --> No Conversion Required

FINAL ANSWER

5.35268063184153 ≈ 5.352681 Watt per Square Meter per Kelvin <-- Effective Heat Transfer Coefficient
