  • Emergency Blanket vs. Standard SheetME 340 Final ProjectScott Pruett & Scott McEuen

  • Experimental SetupGoal: to compare the surface temperatures of an emergency blanket and a sheetProcedure:Turned out lights in CTB 240Scott laid under blankets for 20 min.Measured blanket surface temp. near arm w/ thermocouple

  • Analytical ModelEnergy Balance:

    AssumptionsModel Scott as long cylinderHeat source temp. (surface body temp.) is constantRadiative components for emergency blanket are zero because of polished surface ( 0)Tsurr is the same for all of the walls in the classroomModel radiation as small convex object in large cavity
