Two-dimensional, steady-state conduction occurs in a hollow cylindrical solid of thermal conductivity 14 w/m·k, outer radius 1 m and overall length 5 m, where the origin of the coordinate system is located at the midpoint of the center line. the inner surface of the cylinder is insulated, and the temperature distribution within the cylinder has the form , where -20°c, 150°c/m2, -14°c, -300°c/m2 and and are in meters. (a) determine the inner radius of the cylinder. (b) determine the volumetric rate of heat generation, (c) determine the axial distribution of the heat flux at the outer surface, what is the heat rate at the outer surface? is it into or out of the cylinder?

When temperature of a substance increases, of its particles increase resulting in more between particles. real world applications of thermal expansion absolute zero (-273 degrees c) is the lowest possible temperature on the kelvin scale. it is a measure of where a substance has no kinetic energy. heat is a process of the . energy flows spontaneously from a object to a until equilibrium is reached. heat is measured in heat is transferred throughis a method of heat transfer that occurs between particles of matter that are in direct contact with each other. are poor conductors that impede / reduce the rate of heat transfer. is a method of heat transfer that occurs in fluids (non-solids) by means of currents. real world application of convectiona method of heat transfer through electromagnetic waves. when energy moves from one object to another inside a closed system, no energy is or in the system in the transaction. systems will spontaneously move to a state of organized energy or high disorder over time called
