A brass rod, 1 cm in diameter and 15 cm long, with a tip subject to a breeze with a convection coefficient of 68 W/m2 K in a room where the ambient air temperature is 23°C. The base is 79°C and the tip is designed to maintain a constant temperature of 29°C. The manufacturer finds that the thermal conductivity, in units of W/m*K, to be k(T) 43*In(T)- 128, where T is in units of Kelvin. Plot the temperature profile for...

A 1.70 m cylindrical rod of diameter 0.500 cm is connected to a power supply that maintains a constant potential difference of 13.0 V across its ends, while an ammeter measures the current through it. You observe that at room temperature (20.0 ∘C) the ammeter reads 18.2 A , while at 92.0 ∘C it reads 17.3 A . You can ignore any thermal expansion of the rod. 1) Find the resistivity and for the material of the rod at 20...

The coefficient of linear expansion for some common materials are listed in the table to the right. You would like to design an emergency overheating alarm using one of these materials. In your design, at room temperature (23.0°C), a 7.51 cm long cylinder of the material will sit with one end against a wall and the other just barely touching a button. Once the heat causes the cylinder to lengthen by 0.0258 cm, the button will be activated, turning on...

HW3.3. A cylindrical steel pipe is used to carry water steam with an averaged heat transfer coefficient of h 150 W/m2-K at Ti- 100 °C. The steel pipe goes through the roof of a factory where the ambient temperature is 23°C (To), with a natural heat convection coefficient of 5 W/m2-K. The inner and outer diameters of the steel pipe are 2 cm and 2.2 cm, respectively, and thermal conductivity of the steep pipe is k, -20 W/m-K To prevent...
