Consider a stainless steel spoon (k= 15.1 W/m·C) that is partially immersed in boiling water at 95°C in a kitchen at 25°C. The handle of the spoon has a cross section of about 0.2 cm x 1 cm and extends 18 cm in the air from the free surface of the water. The spoon loses heat by convection to the ambient air with an average heat transfer coefficient of h = 13 W/m2. Assuming steady one-dimensional heat transfer along the...

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...

Water at an average velocity of 3.5 m/s flows through a 5-m-long stainless steel tube (k = 14.2 W/m °C) in a boiler. The inner and outer diameters of the tube are Di = 1.0 cm and Do = 1.4 cm, respectively. If the convection heat transfer coefficient at the outer surface of the tube where boiling is taking place is ho = 8400 W/m2 • °C, determine product of the overall heat transfer coefficient Ui by the inner surface...
