4. The bottle of champagne (specific gravity SGc= 0.96) is under pressure as shown by the

mercury (specific gravity SGm = 13.6) manometer reading. Compute the net force (horizontal,

FH, and vertical, Fy) on the hemispherical end cap at the bottom of the bottle (magnitude of

each component and direction in which it is acting). Workout the force in symbolic fashion by

defining appropriate symbols for variables and heights and then compute the numeric answer.
