# How to Calculate and Solve for Intercept of Density | Konopicky Equation | Powder Metallurgy

**Last Updated on December 10, 2021**

The image above represents intercept of density.

To compute for intercept of density, three essential parameters are needed and these parameters are **Relative Density of Particles (ρ _{t}), Pressing Pressure (P) **and

**Yield Stress Parameter (K).**

The formula for calculating intercept of density:

A = In(^{1} / _{1 – ρt}) – KP

Where:

A = Intercept of Density | Konopicky Equation

ρ_{t} = Relative Density of Particles

P = Pressing Pressure

K = Yield Stress Parameter

Let’s solve an example;

Find the intercept of density when the relative density of particles is 0, the pressing pressure is 4 and the yield stress parameter is 2.

This implies that;

ρ_{t} = Relative Density of Particles = 0

P = Pressing Pressure = 4

K = Yield Stress Parameter = 2

A = In(^{1} / _{1 – ρt}) – KP

A = In(^{1} / _{1 – 0}) – (2)(4)

A = In(^{1} / _{1}) – 8

A = In(1) – 8

A = 0 – 8

A = -8

Therefore, the **intercept of density **is **-8.**
