Prove `S_r *e=w*G`.
We know, the void ratio,e, is defined as a ratio of volume of voids to the volume of solid particles.
`e=V_v/V_s`
`=(V_v/V_w )*(V_w/V_s)`
`=(V_v/V_w)*((W_w/gamma_w)/(W_s/gamma_s))`
`=(V_v/V_w )*(W_w/W_s)*(gamma_s/gamma_w)`
We know,
Specific gravity,`G=gamma_s/gamma_w`
Thus,`e=(V_v/V_w)*(W_w/W_s)*G`
`=(1/S_r)*w*G`
Or, `S_r *e=w*G`
