Sentences with phrase «heat transfer equations»

Here are the basic heat transfer equations.

1) «back radiation» is radiation 2) radiation is included in standard heat transfer equations Therefore «back - radiation» is included in standard heat transfer equations

How about using real heat transfer equations to explain this rather than back radiation.

Further, I repeat that none of the heat transfer equations have an input for back radiation.

Its main argument is that idealized blackbody calculations did not correctly predict the Moon's surface temperatures in the 1960s because other factors besides radiative heat transfer equations actually determine real surface temperatures.

You correctly state that «less energy is needed to to raise one gram of CO2 one °C than one gram of air one °C» but you have simply ignored mass and the fundamental heat transfer equation Q = m x c x delta T.

I have no idea how to post even the simple heat transfer equation and have it look proper.

The cold term has always, always, been right there in the heat transfer equation, always indicating that heat flows only from hot to cold.

Steve I will ask you to show the radiative heat transfer equation in which you input an emission from another body, gas / solid or fluid and show where it lowers the rate of cooling.

There is no input for back radiation in any heat transfer equation so taking as if it does something can not be shown via standard equations.

Not exact matches

In the classic heat - transfer equation, the rate of temperature change depends on how uniformly the thermal energy is distributed through an object.

To explain heat transfer at the microscopic scale, however, Chiloyan and Chen had to dig up the lesser - known form known as microscopic Maxwell's equations.

The amount of energy absorbed depends on the temperature of the absorber, shown to be true by the stefan - boltzmann equation for net transfer of heat.

There are many situations that the primary equations and dimensionless numbers that are used to determine the convective heat transfer from one object to another.

Previously I showed an equation that showed the ratio of convective and radiative heat transfer.

The core science, the radiative transfer equations that determine the way increasing CO2 increases the temperatures gradient between the emission altitude and the surface, derived from military research on heat seeking missile and detection systems.

In normal usage it only applies when the steady state equations won't apply because of the delay in the heat transfer into an object.

That equation is derived from the ratio of the Nusselt and the radiative heat transfer (RHT) rates.

Require more rigorous educational standards for the GCM modelers in the areas of Heat Transfer, Fluid Mechanics, Thermodynamics and non-linear differential equations.

The implication that a modicum of ocean heat is needed to initiate a hurricane needs to be backed up by some back - of - envelope equations that convey heat transfer functions, latent heat, circulation rates etc., to show that the hot ocean is capable to transferring enough heat into a storm to make a difference.

In this case you have the diffusion transfer equation, which similarly has a differential of hot and cold terms describing the heat flow, as does the radiation transfer equation, and we all understand that heat does not physically diffuse from cold to hot and that physical contact between a cold object and warm object does not make the warmer object warmer still.

Heat conduction satisfies a linear equation, but radiative transfer does not.

However, intuition is not as reliable as applying the basic equations of heat transfer.

The only correct approach to calculating heat transfer and temperatures is to apply the relevant equations of conduction, convection and radiation to the particular problem in question.

Although your math seems to work, it appears to me that your conclusion may not be correct, at least if Velasco et al. are; if I interpret their paper correctly, the kinetic - energy profile of their Equation 8 is the maximum - entropy configuration, from which I would conclude that a strictly isothermal microcanonical ensemble will spontaneously undergo (an incredibly small) heat transfer to assume that (ever so slightly non-isothermal) configuration.

This is described by the equation for conductive heat transfer, which in (relatively) plain English says:

If you just use R and L then the hypothesis no longer forbids DLR directly effecting dH and can now be used to heat the ocean directly in equations of heat transfer.

If we solve the differential equations governing heat transfer between atmosphere and oceans and find that heat transfer does in fact occur, in both directions, then we can conclude that the above choices are not mutually exclusive.

In this equation, q is the rate of heat transfer, which is the NET rate of energy transfer.

People write down heat equations for the ocean but then they pretend that they're not really talking about molecular heat transfer but some sort of effective heat transfer so they use much larger thermal diffusion coefficients than the molecular ones.
