Question

Consider a pipe-pipe configuration consisting of concentric steel tubes with an intervening polyurethane foam insulating material with k=0.075 W/m-K. The inner tube is used to transport warm crude oil though ocean
water. The inner steel pipe (k = 35 W/m-K) has an inside diameter of 150mm and wall thickness 10mm while the outer steel pipe has an inside diameter of 250mm and wall same wall thickness as the inside diameter.
Determine the heat transfer in the temperature of the oil is 70°C while the ocean water temperature is at 5°C and provides an external convection heat transfer of 500 W/m² K. The convection coefficient associated
with the flowing crude oil is 450 W/m².K.

A heat recovery device involves transferring energy from the hot flue gases passing through an annular region to pressurized water flowing through the inner tube of the annulus. The inner tube has inner and outer diameters of 24 and 30 mm and is connected by 8 struts to an insulated outer tube of 45-mm diameter. Each strut is 3 mm thick and is integrally fabricated with the inner tube from carbon steel (k = 50 W/m-K). D₂ D₁,2 Dil ↓ Water 1=3 mm Gas h Consider conditions for which water at 300 K flows through the inner tube at 0.161 kg/s while flue gases at 800 K flow through the annulus, maintaining a convection coefficient of 100 W/m².K on both the struts and the outer surface of the inner tube. What is the rate of heat transfer per unit length of tube from gas to the water? Use the Dittus-Boelter equation to obtain the water-side convection coefficient. Determine the rate of heat transfer per unit length of tube from gas to the water, in W/m. 9 = i W/m

40°C water with hwater = 800 W/m² K is flowing in a Pyrex tube. The inner and outer diameters of the tube are 25 mm and 35 mm. A thin metallic heater element bonded to the outer surface of the tube is being used to heat the water by transferring 600 W/m of thermal energy to the water flowing in the tube. The Pyrex tube and heater are covered with a 10-mm thick layer of foam insulation. The outer surface of the foam insulation is exposed to air at T = -5°C with hair = 12 W/m².K. The heater = air element must generate more than 600 W/m, because part of the heat being generated is lost to the air surrounding the foam insulation. Assume kp = 1.30 W/m K for Pyrex and k = 0.026 W/m K for the foam insulation. a) Find the temperature of the heater element needed to transfer 600 W/m of thermal energy to the water in the tube. b) Find the total rate at which the heater element must generate thermal energy.
