1.47 A flat roof is modeled as a flat plate insulated on the bottom and placed in the sunlight. If the radiant heat that the roof receives from the sun is , the convection heat transfer coefficient between the roof and the air is 12 W/m2 K, and the air temperature is , determine the roof temperature for the following two cases: (a) Radiative heat loss to space is negligible, (b) The roof is black and radiates to space, which is assumed to be a black- body at 0 K.
As the temperature differential across a panel increases, A. the rate of heat transfer through the panel will increase. B. the rate of heat transfer through the panel will decrease. C. the rate of heat transfer through the panel will remain unchanged since the temperature difference does not affect the rate of heat transfer.
SUPPOSE THE AMBIENT TEMPERATURE IS 20degrees CELSIUS, AND THE HOT RESERVOIR CONSISTS OF A SPHERICAL TANK WITH A RADIUS OF 4.00 m, THAT ACTS AS AN IDEAL EMITTER OF RADIATION. IF ALL THE RADIANT ENERGY EMITTED BY THE TANK COULD BE CAPTURED, WHAT IS THE AVERAGE AMOUNT OF WORK THAT COULD BE DONE EACH SECOND? ( please only answer if your 100% correct) (show work)
Answer 3-19Please include solution and brief reflection.
The sun's intensity at the distance of the earth is 1370 W/m2W/m2. 30%% of this energy is reflected by water and clouds; 70%% is absorbed. What would be the earth's average temperature (in ∘C∘C) if the earth had no atmosphere? The emissivity of the surface is very close to 1. (The actual average temperature of the earth, about 15 ∘C∘C, is higher than your calculation because of the greenhouse effect.) Express your answer to two significant figures and include the appropriate units.
For the shown quadruple window, find the resistance network if the air inside the glasses have non-zero velocity? 7 convection none of the above 4 conduction, 3 convection 7 conduction 3 conduction, 4 convection
An engineer proposes to decrease the gap between the windows of double pane window to decrease heat transfer. Is it good approach or not? a) Yes, because by this way, less air will be trapped and therefore better insulation b) No, because by this way, radiation heat transfer will increase c) Yes, because by this way, radiation heat transfer will decrease d) No, because by this way, current loops will be created inside the gap e) Not sufficient information
Solve for interface temperatures. Given: heat transfer due to radiation= 507.415 W/m2
Calculate the capillary effect in mm in a glass tube of 2mm diameter, when immersed in (1)water, (2)mercury. The temperature of the liquid is 25ᵒC and the values of surface tensions of water and mercury at 25⁰C in contact with air is 0.0765 and 0.57N/m respectively.

The solar power striking Earth every day averages 168watts per square meter. The highest ever recorded electricalpower usage in New York City was 13,200 MW. A recordestablished in July of 2013. Considering that present technologyfor solar energy conversion is about 10% efficient,from how many square meters of land must sunlight becollected in order to provide this peak power? (For comparison,the total area of New York City is 830 km2.)
