    Calculation of Safety Valve Disc Area

    Unfortunately, I don't have the manufacturer cutsheet. The sectional view of the disc in the diagram I provided is all I have. I'll try and explain it a bit better. In the diagram in my original post, the curve bounded by the red lines (i.e. the hatched part of the cutaway section) is one...

    Calculation of Safety Valve Disc Area

    There are two red lines - a horizontal one and a vertical one in the top diagram. I am trying to have a generic method of calculating the valve disc area for when determining the lift achieved through Trevitesting.

    Calculation of Safety Valve Disc Area

    I am trying to find the area of the curved surface of the safety valve disc shown below (the area between the red lines). Is there a formula for this? I know from the manufacturer that the area is approximately 3372 mm^2, but I am not sure how they got this. Thanks!
