Another factor which helps in the enhancement of thermal conductivity as well as heat transfer is surface area of the material.
( 1 − ϵ B ) / S B Open image in new window; where, the S B is the specific surface area of bed (m3/m2) and, the S is the specific surface area of pellet (m3/m2), the Ap is surface area of pellet while, vp is the volume of pellet ϵB is the porosity of packed bed (m3void/m3r).
The conductivity of membrane was calculated from the following equation: σ = L/RA, where σ is proton conductivity (S/cm), L is membrane thickness (cm), A is surface area of electrodes (cm2) and R is membrane resistance.
where h is the convective heat transfer coefficient, A is surface area of the tube, D is the diameter, and indices 'in' and 'out' indicate the inside and outside of the tube, respectively.
The within-plot variable was surface area of coniferous logs ha−1, since this was the main substrate for a majority of the bryophyte species found.
11, 28 Eq 9 A S is surface area of a vascular source (cm), P is vascular permeability (cm/s), and PC L is partition coefficient.
This is of interest because 4πr^2 is the surface area of a sphere, and we'd be setting r=1, then multiplying r by 4π^2.
The textural properties of B_Sc were a surface area of 398 m2 g−1, a pore diameter of 4.3 nm and a pore volume of 0.43 cm3 g−1.
If the radius of a sphere is 7 centimeters, what is the surface area of that sphere?
Molecular descriptors, including binding energy (BE) and surface area of salts (SA), were calculated by the use of Hyperchem and ChemPlus QSAR programs for Windows.
