Heat and Mass Transfer Thermal diffusivity of a substance is given by (where h = Thermal diffusivity, ρ = Density of substance, S = Specific heat, and k = Thermal conductivity) h = kρ/S h = k/ ρS h = ρS/k h = S/ρk h = kρ/S h = k/ ρS h = ρS/k h = S/ρk ANSWER DOWNLOAD EXAMIANS APP
Heat and Mass Transfer The heat transfer from a hot body to a cold body is directly proportional to the surface area and difference of temperatures between the two bodies. This statement is called Newton's law of heating Newton's law of cooling First law of thermodynamics Stefan's law Newton's law of heating Newton's law of cooling First law of thermodynamics Stefan's law ANSWER DOWNLOAD EXAMIANS APP
