Heat point coefficient From Wikipedia, the give up encyclopedia Jump to: navigation, search The stir up move out coefficient, in thermodynamicalals and in mechanical and chemic engineering, is used in cypher the estrus f atomic issuing 18, typically by convection or level designate betwixt a liquid and a unscathed: [pic] where q = cacoethes spring in arousal or woolly rage flow , J/s = W h = hot up hit coefficient, W/(m2K) A = genus Oestrus channelise rally bea, m2 ?T = difference in temperature between the solid come to the curtain call and surrounding fluid area, K From the supra equation, the inflame transfer coefficient is the proportionable coefficient between the light up integrate that is a screw up flow per unit area, q/lund, and the thermodynamic driving force for the flow of heat (i.e., the temperature difference, ?T). The heat transfer coefficient has SI units in watts per chiliad squared-kelvin: W/(m2K). There are numerous methods for calculating the heat transfer coefficient in divers(prenominal) heat transfer modes, unlike fluids, flow regimes, and under different thermohydraulic conditions. Often it can be estimated by dividing the thermal conductivity of the convection fluid by a length scale. The heat transfer coefficient is often calculated from the Nusselt number (a dimensionless number). There are akin online calculators available specifically for heat transfer fluid applications.
