Conduction and Convection

When energy travels from one object to another it is said to have undergone heat transfer. Heat transfer is nothing but the transfer of thermal energy or internal energy from one thing to another, like e.g., when a vessel with water, kept on top of a burner, heats up because of the flame underneath it.

Question

After going through the production process, thin plates with a length of 0.5m are cooled by suspending
them vertically in a room with still air at 35°C. To maximize production throughput, the plates are hung
as close together as possible. There is a concern however, that if the plates are too close together, the
cooling will take longer, costing the company additional money. If the plates are initially at a
temperature of 75°C, please answer the following:
1. What is the minimum plate spacing that would avoid interference between their free convection
boundary layers?
2. What is the velocity in the x-direction at the upper edge of the plate?

SOLVE STEP BY STEP IN DIGITAL FORMAT The SOLFIES company is dedicated to welding any type of metal, but especially aluminum parts. If the aluminum pieces that are welded come out at 1200°C and to speed up the cooling they are immersed in a tank full of water with a temperature of 0°C. In this case, the heat is transferred from the welded part to the water, causing the temperature to begin to decrease. Taking into account the temperature data of both the piece and the water, in addition to the value of the constant K= 0.02, it is necessary to know how long it takes for the piece to reach a temperature of 20°C in order to handle it and deliver it to the customer. MATH MODEL T'+KT=Tm Solve this differential equation with Euler's numerical method.

Stainless steel type 304 [k = 16.3 W/m-K] from heat treatment was brought to a room @ 27C. It is in cube form and has an edge of side 20cm. Initially, the temp. of the steel from the heat treatment is 500C. The total effective heat transfer coefficient is 18 W/m2-K. How long will it take for the surface of the cube to be within 28 C of the room temp.?
"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)
