For Heat transfer through cylinder tube wall, the temperature is to be a linear function of r (radius) of the tube. Select one: O True O False The conductivity of H20 in solid form (ice) is higher than that of H20 in liquid form (water). Select one: O True O False F, (Correction factor for temperature in some heat exchangers) should be 1.0 or greater than 1.0 in some cases. Select one: O True False
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.
Please answer the two questions under item no.20. Answers are given i want the solutions Thank you. Love u
please write by hand thank you
he night-time chilled water system is not a closed loop system, meaning that some amount of water is lost due to evaporation every night. If it is 96% efficient (i.e. 4% of the water flow rate is dispersed to the outdoor air and needs to be replaced), how much make up water does it need to draw from the municipal water supply daily (in gallons)? Round to nearest integer. (Given: Qheat loss = 1,500,000 Btu) Total gallons in water tank: 1500 gallons//system runs: 10 hours
I posted this question and was told it was too complex to answer. I would like to know why. I would figure that a question meant for a college student could be answered by experts with "Masters and PhDs." Is there a table or chart I need to provide for the refrigerant, R-134A? I just need some help, haha
plzzzzzzz solve it within 30-40 mins I'll give you multiple upvote...ASAP
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. Select one: O True O False
a) In a concentric-pipe heat exchanger, one of the fluids is a condensing vapour and the other is the coolant. Sketch the variation in fluld temperatures of two fluids as they flow through the heat exchanger. Indicate clearly the Inlet and outlet of the coolant and its direction of flow. b) For the case outlined in a) above, the heat-transfer rate, Q, between the two fluids is given by Q =U. Ą ATLI where U, Is the overall heat-transfer coefficient for the heat exchanger, based on the outside surface area of the inner tubo, A, Is the outside surface area of the inner tube and AT Is the relevant temperaturo difference given by ATLM = (T₂-T₁) Tv-T₁ In where subscript v refers to the condensing vapour and subscripts 1 and 2 refer to the Inlet and outlet temperatures respectively of the coolant. 1) State the assumptions used to arrive at the above equation.

Question 1 En. Karim recently bought a heat exchanger for his metal factory. The heat exchanger is a cross-flow type which has cross section size of 1 m X 1 m. En. Karim assigned you to calculate the effectiveness of the heat exchanger. As an engineer, you decided to do the analysis based on section by section. One section of the heat exchanger duct consists 3 cm diameter of 80 tubes. Cold water (cp = 4180 J/kg.K) enters the tube at 18°C. The average velocity of the cold water is 3 m/s. Meanwhile, hot air (cp = 1010 J/kg.K) enters the section at 130°C and 105 kPa. The velocity of the hot air is 12 m/s and air constant, R is 0.287 kJ/kg.K. If the overall heat transfer coefficient is 130 W/m².K, determine i. the mass flow rates of both cold water and hot air, ii. the rate of heat transfer, iii. the effectiveness of the heat exchanger (NTU method), iv. the actual rate of heat transfer, and v. the outlet temperatures of both cold water and hot air.
all questions please thank you so much
a. An air stream passing through a 2-inch (1/6 ft) diameter, thin-walled tube is to be heated by high- pressure steam condensing on the outer surface of the tube at 320 °F. The overall heat transfer coefficient, h between steam and air can be assumed to be 25 Btu/(ft2.hr °F) with the air entering at 100 ft/sec, 10 psia, 40 °F. The air is to be heated to 150 °F. Determine the tube length required. Assuming Rayleigh Line flow, calculate the static pressure change due to heat addition. Also, for the same inlet conditions, calculate the pressure drop due to friction, assuming Fanno flow in the duct with f = 0.018. b. c. d. To obtain an approximation to the overall pressure drop in this heat exchanger, add the two results. Discuss the accuracy of this calculation.
