6. Oxygen used in oxy-acetylene metal cutting was stored in a tank (empty tank weight is 25lb) whose volume is 48ft3. Initially, the gauge pressure reading of the tank was 40psi. After usage, the pressure reading falls to 25psi. Determine the final weight (lb) of the tank after the operation if the temperature in the tank remains constant at 77°F. Draw a figure or FBD that will support the problem. Explain each step by step formula.
(answer number 4-8 & main question) Two vessels of different shape and sizes are connected by means of a pipe with a valve. Vessel A has a diameter of 4 ft and the length is 1.8 m at the given pressure gauge of 1476.4 in Hg and temperature of 82°F. Another vessel spherical in shape contains the same gas at 15,000 torr gauge and 18°C. The valve is opened and when the properties have been determined, it is found out that the gauge pressure is 35.7 kgf/cm2 and the temperature is 21°C. If the barometric pressure is 755 mm Hg, find the following: Volume of Vessel A in in3 - done Pressure at Vessel A in psia - done Temperature at Vessel A in °R - done Pressure at Vessel B in psia Temperature at Vessel B in °R Pressure of the gas when mixed in psia Temperature of the gas when mixed in °R Atmospheric pressure in psi Main Question: What is the diameter of the spherical tank in inches if the gas is carbon dioxide?
Children asked their parent for an ice cream after dinner. They eat their ice cream as long as it does not melt and its structure is solid. The parent drove to buy an ice cream in the grocery store. The ice cream is sold in family sized package. The store keeps the ice cream packages in the freezer until it is sold. The packages are made from polystyrene material and their size is 0.2´0.1´0.07 m3 . The store freezer temperature is kept at -10o C. The ice cream has a solid structure (not melting) as long as its temperature remains below 0o C. The time it takes to reach back from the store is 20 minutes Will the kids eat the ice cream at home? Ice cream properties: k = 2.2 W/mo C, C = 1800 J/kgo C, r = 900 kg/m3 and h = 10 W/m2oC.

Determine the heat added and the final pressure. Your answer
An electric hot water heater consumes 3.1 kilowatts of electricity and converts it to heat. How long will it take the water heater to heat a 67 gallon tank of water from 10 degrees Celsius to 50 degrees Celsius? (1 kilogram of water is 0.37 gallons, 1 Calorie = 4200 J). It may be helpful to refer back to the weekly handout for guidance on this problem. Your final answer should be in minutes (rounded to the nearest 10 minutes).
