In thermodynamics, the heat transfer coefficient or film coefficient, or film effectiveness, is the proportionality constant between the heat flux and the thermodynamic driving force for the flow of heat (i.e., the temperature difference, ΔT).
This calculator can be use to calculate the overall heat transfer coefficient and the heat transfer through a multi-layered wall. The calculator is generic and can be used for metric or imperial units as long as the use of units is consistent.
Feb 2, 2011 · Heat transfer coefficient is a quantitative characteristic of convective heat transfer between a fluid medium (a fluid) and the surface (wall) flowed over by the fluid. This characteristic appears as a proportionality factor a in the Newton-Richmann relation.
Learn how to calculate the heat transfer coefficient for different fluids and solids, and find tables of typical values for various heat exchangers and devices. The web page also explains the units, definitions, and applications of the heat transfer coefficient.
Apr 30, 2024 · This heat transfer coefficient calculator will help you determine the overall heat transfer coefficient or film coefficient. This parameter is vital to most heat transfer calculations and insulation, especially for building walls.
Heat transfer coefficient (h) is defined as the rate of heat convected from fluid to per area of the surface product when the unit temperature gradient exists between fluid and surface (Alvis et al., 2009; Singh and Heldman, 2014 ).
5 days ago · Q = mcΔT, where Q is the symbol for heat transfer (“quantity of heat”), m is the mass of the substance, and ΔT is the change in temperature. The symbol c stands for the specific heat (also called “ specific heat capacity ”) and depends on the material and phase.
