- If temperature difference is doubled whereas thermal conductivity and wall thickness are halved, what will be change in heat conducted through wall?Hello Sir, Good Evening. I have a question in my homework related Heat Transfer lesson. The following below is my question. Please Advice. Thank You "In the steady conduction process, the heat transfer process occurs due to a temperature difference. If we analyze a conductive heat transfer in a gas pipe that is used to convey hot gas, the heat transfer occurs from the hot gas out of the pipe radially. To reduce the rate of heat transfer, what can we do?"Find the heat loss from the fin, answer in MS WORD not in paper please its urgent
- Question six(Heat Transfer) In a heat transfer equipment in a laboratory you used a pipe of outside diameter 9cm to convey steam to reduce the heat outward flow from it to the surroundings. You decided to pad the pipe with two layers of insulating materials each 3cm thick. One from the inside, and the other from the outside. the conductivity of one material being 4times that of the other. I. Show quantitavely that the combined conductivity of the two layers is 28% more when the better thermal insulating material is put on the inside. II. What percentage would the combined conductivity of the two layers be if the better insulating material is now placed on the inside.The schematic below illustrates a tank formed from two zones, i.e. liquid and solid. The tank is heated from the left-side with a time-varying solar heat radiation g,ol =f(t) (Wim), while the right-side is kept at a low temperature T. The top surface of the tank is subjected to the ambient conditions, i.e. (hair & Tair ), while its bottom is thermally insulated. Conjugate heat transfer takes place between the two-physically different zones through the fluid-solid interface separating them, while fluid flow is induced due to buoyancy effects where the buoyancy force is approximated according to Boussinesq formulation Fiuoyaney=P0 Bg(T-To). Explain the following: 1- The assumptions required to simulate the below problem. 2- The conservation equations governing the transport phenomena in each zone. 3- The boundary conditions closing the mathematical model. 4- The discretized form of each conservation equation stated in (point 2) above. 5- The appropriate differencing scheme to be used for…Solve the following problem involving the heat equation:
- A heat transfer mechanism involving heat energy from molecule to molecule mainly in fluids is called?Industrial engg problem.[2] A reservoir of hot water kept at 380K is well insulated except for a copper rod with a cross sectional area of 0.25 m? and a length of 0.50 meters. 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. With a steady flow established, the power fails so that the heating and cooling of the water ceases. What are the…
- 2. A rod that is 1.5 m long is made up of 0.75 m copper and 0.75 m aluminum of equal cross- sectional area and joined end to end. The rod is well insulated that there is no heat loss along the sides. The copper end is at 125 °C while the aluminum end is at 25 °C. Assuming a steady-state heat conduction, find the (a) amount of heat conducted per unit time and area of the rod and (b) temperature I at the copper-aluminum interface.
