This helpful calculator approximates the volume of a given head.

Tank Volume Calculator
U.S. Gallons in Round Tanks
Measurements:
Tank Inside Diameter:
inches
Tank Straight Side Length:
inches
Head Type:
ASME Flanged & Dished:
Dish Radius = Head Diameter
Knuckle Radius = 6% of Head Diameter
Standard Flanged & Dished:
Dish Radius = Head Diameter
Knuckle Radius = 3/4" to 2" depending on Head Diameter
80:10 Flanged & Dished:
Dish Radius = 80% of Head Diameter
Knuckle Radious = 10% of Head Diameter
Hemispherical:
Dish Radius = 1/2 Head Inside Diameter
Knucle Radius = N/A
Elliptical:
Dish Radius ≡ 90% of Head Diameter
Knuckle Radius ≡ 17.3% of Head Diameter
ASME:
10% Dish Radius = Head Diameter
Knuckle Radius = 10% of Head Diameter
