Consider a 4-m-diameter spherical tank initially filled with liquid nitrogen at 1 atm and 196°C. The tank is exposed to 20°C ambient air with a heat transfer coefficient of 25 W/m² °C. The temperature of the thin-shelled spherical tank is observed to be almost the same as the temperature of the nitrogen inside. Disregarding any radiation heat exchange, determine the rate of evaporation of the liquid nitrogen in the tank as a result of the heat transfer from the ambient air, since the heat of vaporization of 198 kJ/kg at 1 atm. Tair = 20°C N, vapor 1 atm Liquid N₂ -196°C

hand written plz Answer the following questions using the information provided in this unit. Know and Understand 1. True or False? The primary purpose of section views is to help feature exterior detail without using hidden lines. For the next three terms, match the three types of lines to the three descriptions. Answers are used only once. 2. Cutting-plane line 3. Section line 4. Short break line A. Not exclusive to section views, but needed for broken- out sections. B. Drawn thick in a view adjacent to the section view. C. Drawn thin, and usually continuous, but sometimes dashed. 5. Of the following, which is not a type of section view featured in this unit? A. Full B. Half C. Quarter D. Offset 6. True or False? The preferred dividing line between the two halves of a half-section view is the visible line. 7. An object with a number of odd features, such as spokes or holes, often has a(n) section so the odd features can be rotated around the axis into a vertical cutting plane,…
