    Hi

    How do I calculate and/or is there a formula and/or rule of thumb for the minimum distance between two holes in a glass pane?

    Assume glass thickness plays a role?

    depending on the thickness of the glass and two how much pressure there would be on the glass. for a 10mm glass I would say you can have the hole about 10mm away from the edge or from the next hole. just make sure you set your drilling machine to very low rpm when drilling your glass (less than 500rpm recommended )
    but if the glass you are drilling is on the long side of the tank I wound suggest drilling the wholes as far as possible from each other and also to avoid drilling along the vertical centre where the most pressure would be once the tank is full
