What is lattice parameter?
The lattice parameter is a physical dimension and angle that determines the geometry of unit cells in a crystal lattice. It is proportional to the distance between atoms in the crystal. A simple cubic crystal has only one lattice constant, while in general lattices in three dimensions have six lattice constants: the lengths a, b, and c of the three cell edges meeting at a vertex, and the angles,, and between those edges.
How to Calculate Pressure Inside Grain?
Pressure Inside Grain calculator uses Inside pressure of Grain = External Pressure of Grain+(4*Specific Surface Energy)/Size of Grain to calculate the Inside pressure of Grain, The Pressure Inside Grain formula is defined as a measure of how the internal energy of a system changes with the changes in external pressure, surface energy and grain size. Inside pressure of Grain is denoted by P_{i} symbol.
How to calculate Pressure Inside Grain using this online calculator? To use this online calculator for Pressure Inside Grain, enter External Pressure of Grain (P_{e}), Specific Surface Energy (γ) & Size of Grain (Φ) and hit the calculate button. Here is how the Pressure Inside Grain calculation can be explained with given input values -> 2E+8 = 20+(4*50)/1E-07.
