Thermal jackets are typically put on cryogenic storage tanks to minimize the heat transfer gains from the surroundings. Consider a cylinder container that is 1.5 m long made from steel (k= 750 W/m.K) with an inner diameter of 0.5 m and outer diameter of 0.7 m. If the liquefied natural gas (LNG) inside the cylinder is maintained at 90 K, ambient conditions are T,ms = 20 °C, h = 7 W/m².K. What is the required thermal jacket thickness to maintain the outer temperature of that jacket of 15 °C? (Take a thermal conductivity of the insulation to be king = 0.015 W/m.K).
