Consider the camper below in the same conditions but now wit

Consider the camper below in the same conditions, but now with better equipment. She is inside a fluffy down sleeping baa, and laying on a thick closed-cell foam pad with a nylon tarp shelter overhead. For each of the three pieces of equipment (labeled below): a) What effect will each have on the exchange of heat between this happy camper and her environment? b) Would a different material or configuration work better? Write your answers below, thoroughly describing the affect of each new piece of equipment. NOTE: you may want to research the properties of these materials to help answer this question if you are unfamiliar with them, but a numeric answer is not required.)

Solution

The nylon tarp shelter will protect the hiker from the elements of the environment like gusty wind, rain etc and hence prevent body temperature from falling.

The down sleeping bag is an insulator. Thus it prevents the heat from the body from reaching the enviroment and also prevents the temperature of the surrounding from affecting the camper.

The foam pad prevents moisture from the ground from affecting the sleeping bag while providing insulation from the ground too.

The only change I would recommend is using a double walled tent rather than tarp shelter. In double walled tents one is saved from the possibility of the interior of the tent becoming moist because of condensationon the inner surface of the tent. The double wallled structure prevents this from happening. Though a point to be noted would be that tents could be much much heavier than tarps. So there is a flipside to using one.
