My question is regarding balance ratios for gas-lubricated
non-contacting dual-balanced mechanical seals.  In my question, the
hydraulic area is what presses the mating surfaces together, the
sliding area is the mated area and the groove area is what lifts the
seal. What ratios are typically used between the hydraulic area, the
sliding area and the mated groove area? It appears to me the ratio is
generally 3-8-2 for an overall balance ratio of 2/3.
