h3. Input Definitions


h5. Inputs Needed to Call the Chemical Stock Tank Barrels Function

* origin - a 3*1 matrix with user defined x,y,z positions corresponding to origin. The origin is located at the top right corner of the platform.

* disp - displacement between the edge of the drum containing the chemical stock solution (sometimes also refered to as the chemical stock barrel) and the edge of the platform.

* thick - specifies the thickness of the platform.

* walkway - the width of a walkway space on the platform, so that the plant operater can walk on the platform next to the chemical stock drums/barrels

* R - chemical stock drum radius/ chemical stock barrel
radius

* H - chemical stock drum radius/ chemical stock barrel height
