Due higher viscosity, the heat-transfer coefficient of moving liquid hydrocarbons is generally higher than that of moving water Select one: O True O False The proper strategy to enhance heat transfer of a heat exchanger is trying to increase the heat transfer coefficient of the side with the lower heat resistant. Select one: O True O False For the universal 3-D heat transfer equation (see topic 7 in URCourses notes), we have to simplify by eliminating terms that are zero or near zero first, and then we can only use numerical methods (such as finite difference) to solve those problems.

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.
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?"

A conditioned space has a calculated heat loss at the design maximum heating day of 10,000 BTUs / Hr to maintain an interior temperature of 70 F. We will use a hydronic baseboard style convector to heat the space. The style we have chosen comes in standard lengths. At rated temperature and flow of hydronic heating fluid for each 1 foot of length the heater will add 750 BTUs /Hr to the room. What length of heater can just maintain the temperature on the worst day? For this example we are ignoring other sources of heat loss such as ventilation or drafts.

MATLAB coding required for plot Hot air for a large scale drying operation is to be produced by routing the air over a tube bank, while products of combustion are routed through the tubes. The surface area of the cross-flow heat exchanger is A = 25 m2, and for the proposed operating conditions, the manufacturer specifies and overall heat transfer coefficient of U = 35 W/(m2 K). The air and the combustion gases may each be assumed to have a specific heat of cp = 1040 J/(kg K). Consider conditions for which combustion gases flowing at 1 kg/s enter the heat exchanger at 800 K, while air at 5 kg/s has an inlet temperature of 300 K. (a) What are the air and gas outlet temperatures? (b) Explore the effect of changes in surface area and heat transfer coefficient on the air outlet temperature for UA values from 500 to 2500 W/K. Discuss the implications and back up the discussion with an appropriate plot.
