A well-mixed, insulated water storage tank is to be maintained at internal temperature 60°C. The environmental temperature around the tank varies from -25°C to 30°C. The tank's exterior surfaces (total = 125 m²) have four different levels of insulation as indicated in the table. Component Surface A Surface B Surface C Surface D Surface A Surface B Say that just one surface can be selected to have its insulation upgraded such that its effective RSI would be doubled. Which should be selected to achieve the greatest reduction in heat loss? Surface C Surface Area, Effective RSI, m² m². C/W 5.0 30.0 Surface D 30.0 60.0 0.5 2.5 15.0 10.0
