case 3 (Red mark)
should conduct explicit finite difference method and compare with the best-case scenario (Scenario 1 or 2). Compare your design to the insulated reusable bottles currently available on the market. The insulated reusable bottle must perform well, and it must be suitable for purchase and use as a household item, durable, easy to manufacture, and affordable. Justify your recommendation.
Assumptions: 1) Heat transfer is one-dimensional; 2) Thermal properties, heat transfer coefficients, and the surrounding air and surface temperatures remain constant during the process; 3) The thermal contact resistance between the fluid and the walls (plate/glass/paper, etc.) is negligible. 3 Conduct the analysis according to the following scenario: if the bottle is to be used for hot a fluid (hot coffee with a temperature of 96°C; temperature of the coffee just after pouring in the bottle at t=0). The bottle is to be used by a baggage handler driving an open wagon at the O’Hare International airport in Chicago in the month of January (-5 °C)). Take the ambient surrounding surface temperature to be -5°C and the convection heat transfer coefficient to be 22 W/m2 *K in the analysis.
