Enter a value for all fields

The **Capacity of a Dished End (Torispherical) Tank** calculator computes the volume of a cylindrical tank with torispherical heads based on the length (L) and diameter (D) of the tank and the crown radius (R) and knuckle radius (a) of the torispherical heads.

**NOTE: Default units have been updated to millimeters for inputs and cubic centimeters for outputs. Both can be changed.**

**INSTRUCTIONS:** Choose units and enter the following:

- (
**L**) Length of Tank - (
**D**) Diameter of Tank - (
**R**) Interior Crown Radius of Torispherical Head - (
**a**) Interior Knuckle Radius of Torispherical Head

**Volume of a Cylindrical Tank with Torispherical Heads (V):** The volume is returned in cubic centi-meters rounded to the nearest 1/10000^{th}. However, the volume can be automatically converted to other volume units (e.g. liters, cubic feet, gallons, barrels) via the pull-down menu.

The relationship between the diameter of a torispherical head and the height of the head is:

`h = R - sqrt((R-a)^2 - (D/2 -a)^2)`

where:

- h = torispherical head height
- R = crown radius
- a = knuckle radius

**Capacity of a Dished End Tank**: Computes the volume of a cylindrical tank with torispherical heads based on the length and diameter of the tank and the crown radius and knuckle radius of the torispherical heads.**Torispherical Head Volume**:**CORRECTED.**Computes the volume and diameter of an torispherical head (dish-head) based on the crown radius, knuckle radius and the height.**Torispherical Head Volume and Height**: computes the volume of an torispherical head based on the crown radius, knuckle radius and the Diameter. It also computes the head height.**Volume of a Torispherical Head Cylindrical Tank**: Computes the volume of a cylindrical tank with torispherical heads (dish end) based on the length and diameter of the tank and the crown radius and knuckle radius of the torispherical heads.**Mass of the Contents of Torispherical Head Tank**: Computes the weight / mass of the contents of tank with torispherical heads based on the volume and density of the contents.
