In a food processing facility, a spherical container of inner radius n = 40 cm, outer radius r2 = 41 cm, and thermal conductivity k = 1.5 W/m 'C is used to store hot water and to keep it at 100°C at all times (see Figure Q2). To accomplish this, the outer surface of the container is wrapped with a 500-W electric strip heater and then insulated. The temperature of the inner surface of the container is observed to be...

Problem 2. (20 pts) As shown in the figure, uniform generation occurs inside the spherical core with a radius n due to reactive heating at a rate of q 10 W/m3. The thermal conductivity of the reactive material is 20 Wm. K. The spherical shell 1Sr is made of stainless steel (s.s.) with a thermal conductivity k2 -15 W/m K. Given 0.5 m and k2 72=0.6 m, water flows outside to cool the s.s. shell at To-25°C and h =...

Heat transfer. I just need the right choice
Qu Choose the correct answer was The handle of a saucepan, 30 (6 cm long and 2 cm in diameter is partially immersed in boling water at 100°C. The average unit conductance over the handle surface is 735 Wim2K in the kitchen air at 24C. The cook is likely to grasp the last 10 cm of the handle and hence, the temperature of this portion should not exceed 32C. What should be...

2. (10 points) A pharmaceutical fluid is sterilized by heating it from 25 to 75 °C as it moves at 0.2 m/s through a straight thin-walled stainless steel tube of 12.7-mm diameter that is 10 m long. A uniform heat flux is maintained by an electric resistance heater wrapped around the outer surface of the straight tube. The pharmaceutical fluid properties may be approximated as: p = 1000 kg/mº, cp = 4 kJ/kg-K, u = 2.102 kg/s-m, k = 1...
