What is Heat Transfer?

Heat transfer is a discipline of thermal engineering that concerns the generation, use, conversion, and exchange of thermal energy between physical systems. Heat transfer is classified into various mechanisms, such as thermal conduction, thermal convection, thermal radiation, and transfer of energy by phase changes.

Define Thermal Conductivity & Factors affecting it?

Thermal conductivity is defined as the ability of a substance to conduct heat. Factors Affecting The Thermal Conductivity are: Moisture, Density of material, Pressure, Temperature & Structure of material.

How to Calculate Viscosity of Film given Mass Flow of Condensate?

Viscosity of Film given Mass Flow of Condensate calculator uses Viscosity of Film = (Density of Liquid*(Density of Liquid-Density of Vapor)*[g]*(Film Thickness^3))/(3*Mass Flow Rate) to calculate the Viscosity of Film, The Viscosity of Film given Mass Flow of Condensate formula is defined as as the function of Viscosity of film, mass flow rate of condensate, density of liquid, density of vapor. In two-phase heat transfer applications that do not contain a wick structure, a thin film of liquid is often present enclosing either partially or completely around the vapor bubbles. Film thickness would be the thickness of this thin layer of liquid. Also, there are applications that only use a thin layer of liquid for heat transfer applications. This used as it is shown to have enhanced heat transfer capabilities in certain applications. Viscosity of Film is denoted by μ_f symbol.
