STEP 1: Convert Input(s) to Base Unit

Equivalent Radiative Heat Transfer Coefficient: 1.162423 Watt per Square Meter per Kelvin --> 1.162423 Watt per Square Meter per Kelvin No Conversion Required
Average Temperature of Absorber Plate: 107.69 Kelvin --> 107.69 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
Average of Inlet and Outlet Temperature of fluid: 14 Kelvin --> 14 Kelvin No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

T_bm = (h_r*T_pm+h_fb*T_f)/(h_r+h_fb) --> (1.162423*107.69+3.2*14)/(1.162423+3.2)

Evaluating ... ...

T_bm = 38.9648901241351

STEP 3: Convert Result to Output's Unit

38.9648901241351 Kelvin --> No Conversion Required

FINAL ANSWER

38.9648901241351 ≈ 38.96489 Kelvin <-- Mean Temperature of Plate below
