Temperature gradient Sentence Examples

These equations can be made to represent the state of convective equilibrium of the atmosphere, depending on the gas-equation p = pk =RA (6) where 0 denotes the absolute temperature; and then d9 d p R dz - dz (p) n+ 1' so that the temperature-gradient deldz is constant, as in convective equilibrium in (I I).

From the gas-equation in general, in the atmosphere n d dp _ I dp 1 de _ d0 de i de (8) z p dz-edz-p-edz-k-edz' which is positive, and the density p diminishes with the ascent, provided the temperature-gradient de/dz does not exceed elk.

The thermal conductivity of the substance is the constant ratio of the rate of transmission to the temperature gradient.

The measurement of the temperature gradient in the plate generally presents the greatest difficulties.

It is the most convenient method, in the case of good conductors, on account of the great facilities which it permits for the measurement of the temperature gradient at different points; but it has the disadvantage that the results depend almost entirely on a knowledge of the external heat loss or emissivity, or, in comparative experiments, on the assumption that it is the same in different cases.

The heat transmitted through the plane x is equal per unit area of surface to the product of k by the mean temperature gradient (de /dx) and the interval of time, T - T'.

The mean temperature gradient is found by plotting the curves for each day from the daily observations.

Since the only cause for these convection currents is the statical instability produced by radiation, and the rapid stifling of radiations within the body produces there a temperature gradient falling very slowly, they would be for the most part extremely slight.

The temperature gradient at the confines of the photosphere must certainly ascend sharply at first.

For simplicity in the diagram the temperature gradient has been taken as uniform, and the specific heat s= constant, but the total P.D.

One involves experimental and numerical research into the behavior of liquid gallium under the combined action of a temperature gradient and a magnetic field.

There also exists a temperature gradient from the bore to the rim of the disk.

The heat loss through the cylinder wall leads to a significant temperature gradient in the boundary layer.

Additionally the mean temperature gradient after cold exposure was reduced after laser irradiation, while the number of fingers showing prolonged rewarming was unaffected.

In either case the growing disturbances will tend to erode the gradient that is producing them, namely the temperature gradient.
