Students have asked these similar questions
for the plan shaws the below calculate heating and cooling load
for the plan The building should have an orientation (south or north ..... etc.), windows, doors ...... etc. and their locations.
Then estimate the cooling and heating loads
Latitude angle for Duhok = 37.1(2 (Assume 36)
Outdoor design dry bulb temperature for Duhok/
Summer = 46 C Outdoor design wet bulb
temperature for Duhok/ Summer = 232]C Outdoor
design dry bulb temperature for Duhok/ Winter = -
4]C Outdoor design wet bulb temperature for
Duhok/Winter = - 5.3[2]C Inside design conditions /
Summer and Winter = 24 ?]C db and 50% RH Daily
range =15 C
Color correction factor for wall = 0.65
Color correction factor for roof = 0.5
The window having double glazing window
Select the suitable materials for the walls and roof.
No exterior shading with interior shading
Assume the cooling load at 2:00 PM, 21 July as maximum
Estimate the cooling and heating loads.
Note: Assume any missing data
Ventilation: The plant must have adequate ventilation to prevent the buildup of oxygen gas, which can be flammable and cause potential hazards.
Electrical equipment: All electrical equipment used in the plant must be designed for use in a hazardous environment.
Structural requirements: The building must be designed to withstand the weight and pressure of the refrigeration and cryogenic systems, as well as the potential stresses caused by temperature fluctuations.
Please elaborate it well, this is an indoor consideration when designing cryogenic plant. you can add more.
Must answer all the questions strictly. Otherwise dont attempt.

The rod is also well insulated except for its ends and the other end is in a second well insulated reservoir of water held at 280K. a) Determine the rate of heat flow through the copper rod. b) Calculate the temperature at the center of the rod (0.25 meters from either end). Then extend the process to find the temperature at each point 0.1m along the rod. c) Calculate the rate of entropy change at each end of the rod. d) Using your answer for (c), show that the statements "Heat flows spontaneously from high temperature to low temperature." and "Any spontaneous process causes the entropy of the universe to increase." are logically equivalent for situations with heat flow. e) Each reservoir of water holds 1 m of water.

- A package of frozen fish sticks have different instructions when they are heated up on the stove as compared to using the oven. Stove: Heat over medium flame for 2 minutes. Then flip the fish sticks (turn them over) and heat them for another two minutes. Oven: Preheat the oven to 375 F. Put them on a metal baking sheet for 15 minutes. a. Explain why the instructions have you flip the fish sticks over when you’re heating them with the stove, but not with the oven. b. If you follow the oven instructions, the side of the fish sticks touching the metal baking sheet will cook more than the top side of the fish sticks.
