The R-Value of an Insulating Material Is the Thickness of the Material

question 19

Multiple Choice

The R-value of an insulating material is the thickness of the material divided by its thermal conductivity. When an insulating material consists of three layers with R-values R1, R2 and R3, the overall R-value of the insulation is given by:

• A)R = R1 + R2 + R3.
• B) \(R=\frac{R_{1} R_{2}+R_{1} R_{3}+R_{2} R_{3}}{R_{1}+R_{2}+R_{3}}\) .
• C) \(R=\frac{R_{1} R_{2} R_{3}}{R_{1} R_{2}+R_{1} R_{3}+R_{2} R_{3}}\) .
• D) \(\frac{1}{R}=\frac{1}{R_{1}+R_{2}+R_{3}}\) .
• E) \(\frac{1}{R}=\frac{1}{R_{1}}+\frac{1}{R_{2}}+\frac{1}{R_{3}}\) .
