Challenge Problems
Push your limits with advanced challenges
A transparent polycarbonate sheet has an absorptivity of 0.15 and a reflectivity of 0.10. Calculate the transmissivity and analyze how this affects its use in greenhouses.
💡 Hint: Use the formula for transmissivity carefully.
You are tasked with designing a solar panel array. If the desired absorptivity is 0.8, what maximum transmissivity can the covering layer have? Discuss the design choices you would make based on this.
💡 Hint: Rearrange the energy balance equation to find the limits on your design.
