Hello, Please listen to me carefully. I need "What is the temperature of the Sun (google for the answer)? What is there-entry temperature of the Space Shuttle (google for the answer)? Whydon’t you burn up at the reentry temperature that you’ve calculated for thisMach 20 flow? The answer to this question will lead you to recognize thatFigure 4.6 is wrong and that the body should actually re-enter the Earth’satmosphere in the opposite direction. (ie.. blunt/flat surface first.)" to be answered based on the main question ******Dont solve for the main question as I dont want it. ******
An arc welding operation on nickel performs a groove weld, whose cross-sectional area = 20.0 mm2. The melting point of nickel Tm = 1725° Travel velocity = 4.0 mm/sec. Heat transfer factor = 0.82, and melting factor = 0.70. Determine the rate of heat generation required at the welding source to accomplish this weld.
hello, where did you get the values from the first equation in step 2? and also, what formula did you use for this? thank you :)
My buddy is starting to get hypothermic (body temperature 306 K) during an epic backcountry ski adventure. Since I'm quite warm (body temperature 310 K), I decide to get in a sleeping bag with him to try and warm him up. What heat transfer mechanism will be most responsible for heating him up? For simplicity, ignore any internal temperature differences across my body (that is, assume my skin temperature is also 310 K). Use numbers to support your answer (for human skin, you can use the following values: surface area A = 1:50 m2, emissivity = 0:970, thickness d = 0:0250 m, thermal conductivty 0:200 JmsK)
