3.Question (a) Look up the definition of unit for clothing insulation, called “clo” value. Convert 1.5 clo to a value with an unit in international standard. (b) In the winter, people wear more cloth to keep themselves warm. You have the option of wearing 2 jackets that are 0.3 cm thick or 1 jacket that is 0.6 cm. Assume they are made of the same material and neglect any effect from cloth openings. Which option should you choose to keep you warm? Draw a thermal circuit to help with your discussion.
