"You did calculations using the simplified HAZ time-temperature formulas, assuming 3D heat flow, and are presenting your final internship conclusions to management. You realize with horror, in the middle of your presentation, that you forgot to label your calculated curves (below). Which curve is which? Pick the best answer A: "Plot 1 is HYPERFILL® and Plot 2 is p-GMAW. Since HYPERFILL® has the higher heat input, it cools more slowly." B: "Plot 2 is HYPERFILL® and Plot 1 is p-GMAW. Since HYPERFILL® has the faster travel speed of the two processes, it cools faster." C: "Plot 1 is p-GMAW and Plot 2 is HYPERFILL®. Since p-GMAW has the slower travel speed, it cools more slowly." D: "Plot 2 is p-GMAW and Plot 1 is HYPERFILL®. Since p-GMAW has the lower heat input, it cools faster" Both (A) and (D)
Please solve this problem, Thank you very uch
After you exercise for a while, you may notice that your skin turns red. (A) How is the blood flow in your limb changes as a response to the exercise? When your skin turns red, how has the temperature changed at the skin surface (Tskin)? (B) During exercise, does the total heat generation rate inside your body increase or decrease from that in normal conditions? (C) What is the relationship between the total heat generation rate and the total heat loss from the skin surface to the environment by convection? Neglect sweating and radiation. (D) The total heat loss from the skin surface to the environment is hA(Tskir-Tair). Based on this convection equation and results in (C), how has the skin temperature changed during exercise? Does Tskin increase or decrease from that in normal conditions? Is this consistent with that in (A)?
Hi, please help me with this question thankyou
Air has a very low thermal conductivity. This explains whywe feel comfortable wearing short sleeves in a 20°C environment eventhough our body temperature is 37°C. Material objects feel cooler to ourimmediate touch than the air, owing to relatively high thermal conductivities.(a) Touch a few surfaces in a room-temperature environment andrank them in order of which feel the coolest to which feel the warmest.Objects that feel cooler have larger thermal conductivities. Consider awood surface, a metallic surface, and a glass surface, and rank these inorder from coolest to warmest
