Where:

Q = Heat Steady State Transfer (W)

A = Area (m^{2})

L_{n} = Length (m)

k = Thermal Conductivity (W/m · °C)

T_{∞1} = Temperature (°C)

T_{∞2} = Temperature (°C)

T_{1} = Temperature (°C)

h_{1} = Heat Transfer Coefficient (W/m^{2} · °C)

h_{2} = Heat Transfer Coefficient (W/m^{2} · °C)

R_{conv, 1} = Thermal Resistance (°C/W)

R_{conv, 2} = Thermal Resistance (°C/W)

R_{glass1} = Thermal Resistance Glass (°C/W)

R_{glass2} = Thermal Resistance Glass (°C/W)

R_{air} = Thermal Resistance Glass (°C/W)
