Heat Transfer Coefficient given Local Heat Transfer Resistance of Air Film Solution

STEP 0: Pre-Calculation Summary

Formula Used

Heat Transfer Coefficient = 1/((Area)*Local Heat Transfer Resistance)
h_ht = 1/((A)*HT_Resistance)
This formula uses 3 Variables

Variables Used

Heat Transfer Coefficient - (Measured in Watt per Square Meter per Kelvin) - The Heat Transfer Coefficient is the heat transferred per unit area per kelvin. Thus area is included in the equation as it represents the area over which the transfer of heat takes place.
Area - (Measured in Square Meter) - The area is the amount of two-dimensional space taken up by an object.
Local Heat Transfer Resistance - (Measured in Kelvin per Watt) - Local Heat Transfer Resistance is the ratio of the temperature difference, dT, to the heat transfer Q. This is analogous to Ohm's law.

STEP 1: Convert Input(s) to Base Unit

Area: 0.05 Square Meter --> 0.05 Square Meter No Conversion Required
Local Heat Transfer Resistance: 13.33 Kelvin per Watt --> 13.33 Kelvin per Watt No Conversion Required

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 Heat Transfer Coefficient given Local Heat Transfer Resistance of Air Film?

Heat Transfer Coefficient given Local Heat Transfer Resistance of Air Film calculator uses Heat Transfer Coefficient = 1/((Area)*Local Heat Transfer Resistance) to calculate the Heat Transfer Coefficient, The Heat Transfer Coefficient given Local Heat Transfer Resistance of Air Film formula is defined as inverse of the product of area of heat transfer and local heat transfer resistance. The convective heat transfer coefficient depends on the fluid’s physical properties and the physical situation. The convective heat transfer coefficient is not a property of the fluid. It is an experimentally determined parameter whose value depends on all the variables influencing convection, such as the surface geometry, the nature of fluid motion, the properties of the fluid, and the bulk fluid velocity. Typically, the convective heat transfer coefficient for laminar flow is relatively low compared to the convective heat transfer coefficient for turbulent flow. This is due to turbulent flow having a thinner stagnant fluid film layer on the heat transfer surface. Heat Transfer Coefficient is denoted by h_ht symbol.
