Explanation:a) the steady-state, 1-D incompressible and no energy generation equation can be expressed as follows:b) For a transient, 1-D, constant with energy generationsuppose T = f(x)Then; the equation can be expressed as:where; = heat generated per unit volume = Thermal diffusivity c) The heat equation for a cylinder steady-state with 2-D constant and no compressible energy generation is:where;The radial directional term = and the axial directional term is d) The heat equation for a wire going through a furnace is:since;the steady-state is zero, Then:'e) The heat equation for a sphere that is transient, 1-D, and incompressible with energy generation is:
