Variables Used

Collector Efficiency Factor - Collector efficiency factor is defined as the ratio of the actual thermal collector power to the power of an ideal collector whose absorber temperature is equal to the fluid temperature.
Overall Loss Coefficient - (Measured in Watt per Square Meter per Kelvin) - Overall loss coefficient is defined as the heat loss from collector per unit area of absorber plate and temperature difference between absorber plate and surrounding air.
Outer Diameter of Absorber Tube - (Measured in Meter) - Outer diameter of absorber tube is the measurement of the outside edges of the tube passing through its center.
Inner Diameter Absorber Tube - (Measured in Meter) - Inner diameter absorber tube is defined as the inside diameter of absorber tube.
Heat Transfer Coefficient Inside - (Measured in Watt per Square Meter per Kelvin) - Heat transfer coefficient inside is the heat transfer coefficient on the inside surface of the tube.

STEP 1: Convert Input(s) to Base Unit

Overall Loss Coefficient: 1.25 Watt per Square Meter per Kelvin --> 1.25 Watt per Square Meter per Kelvin No Conversion Required
Outer Diameter of Absorber Tube: 2 Meter --> 2 Meter No Conversion Required
Inner Diameter Absorber Tube: 0.15 Meter --> 0.15 Meter No Conversion Required
Heat Transfer Coefficient Inside: 1.75 Watt per Square Meter per Kelvin --> 1.75 Watt per Square Meter per Kelvin No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

F′ = 1/(U_l*(1/U_l+D_o/(D_i*h_f))) --> 1/(1.25*(1/1.25+2/(0.15*1.75)))

Evaluating ... ...
