Question 2 33 pts TT T. An iron pipe is covered by ceramic insulation. The inner radius, ri of the metal pipe is equal to 0.04 m, while its outer radius, re, is equal to 0.10 m. On the other hand, the ceramic insulation has a thickness of 0.04 m. If the inner and outer temperatures, Ti and To, are kept constant at 400 K and 323 K respectively, find Tc in Kelvin. The length of the pipe is 10...

Question 3 34 pts ro 1 ri = 0.05m A pipe with surface temperature T1 - 458 K is wrapped with 0.04 m of glass fiber pipe insulation. The outer surface temperature of the insulation, T2 is equal to 347 K and its emissivity is equal to 0.68. The insulation is also subject to natural convection with a bulk fluid temperature of 298 K and h = 4 W/m2-K. For a pipe length of 100 m, and assuming that the...

ro ri = 0.05m 1 A pipe with surface temperature T1 = 380 K is wrapped with 0.09 m of glass fiber pipe insulation. The outer surface temperature of the insulation, T2 is equal to 354 K and its emissivity is equal to 0.74. The insulation is also subject to natural convection with a bulk fluid temperature of 298 K and h = 1W/m2-K. For a pipe length of 100 m, and assuming that the room temperature is similar to...
Problem 3 (30): Steam at Too,1 340 °C flows in a cast iron pipe [k- 80 W/m.°C] whose inner and outer diameter are Di 6 cm and D2 -8 cm, respectively. The pipe is covered with a 4-cm thick glass wool...
Problem 3 (30): Steam at Too,1 340 °C flows in a cast iron pipe [k- 80 W/m.°C] whose inner and outer diameter are Di 6 cm and D2 -8 cm, respectively. The pipe is covered with a 4-cm thick glass wool insulation [k-0.05 W/ m°C]. Heat is lost to the surroundings at Too,2 - 21°C by natural convection and radiation, with a combined heat transfer coefficient of h- 18 W/m2 °C. Taking the heat transfer coefficient inside the pipe to...
