| 1. | Before the critical radius is reached any added insulation increases heat transfer.
|
| 2. | For insulated cylinders, the critical radius is given by the equation
|
| 3. | For insulated cylinders, a " critical radius " must be reached.
|
| 4. | This implies that adding insulation below a certain "'critical radius "'actually increases the heat transfer.
|
| 5. | The planets have migration might become inefficient near the critical radius, leaving planets just outside this radius.
|
| 6. | The critical radius r _ c is found by setting the derivative of G equal to zero
|
| 7. | At the critical radius r = r _ c, the vector field \ partial _ \ phi becomes null.
|
| 8. | This equation shows that the critical radius depends only on the heat transfer coefficient and the thermal conductivity of the insulation.
|
| 9. | For our sun, that critical radius is calculated to be about three kilometers ( 1.86 miles ), " the dictionary says.
