Answer all questions 1. A convergent-divergent nozzle expands air at 6.89 bar and 427°C into a space at 1 bar. The throat area of the nozzle is 650 mm and the exit area is 975 mm². the exit velocity is found to be 680 m/s when the inlet velocity is negligible. Assuming that friction in convergent portion is negligible, calculate : [CLO 2:C4] i) critical pressure ii) critical temperature iii) critical velocity iv) the mass flow through the nozzle

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.
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).
