VolumeHorizontalTank (Function)

This function will calculate the amount of fluid in a horizontal tank. The calculation is based on the tank possessing uncurved ends and being perfectly circular in shape.

Input:

R : DINT (0..2147483648)

Radius of the tank in millimeters.                

L : DINT (0..2147483648)

Length of the tank in millimeters.

H : DINT (0..2147483648)

Height of the fluid in the tank (if "H" equals "R", the tank is completely full) in milliliters.

Returns: DINT

The amount of fluid contained in the tank in milliliters.

Declaration:

FUNCTION VolumeHorizontalTank : DINT;
VAR_INPUT
R : DINT;
