Conical Length, Conical Height and Apex Angle
Conical Length, Conical Height and Apex Angle
(OP)
Hi all,
I'm really looking forward to deeply understand cone length, cone height and half-apex angle.
From my study I found out that cone length is the length along the conical section itself and cone height is the height of the cone between the smaller diameter of the cylinder and the larger diameter of the cylinder. Are my understanding correct? If not please elaborate to me what is the difference between these two and method of determine them.
Second thing is the half-apex angle, I'm not quite familiar with these. For example the drawing stated 10 degree angle then when I model it in PV Elite the angle is way off more than 30 degrees as mentioned inside ASME.
Please help me understand this terms and any useful links for me to really understand.
Thank you.

Also, to my experience, eccentric cones (see UG-36) are not recognized in PVE / CodeCalc. They can be run, if one knows how.
I hope you are not attempting to operate the software without an understanding of the rules behind it.

As PVE goes eccentric cones can be done however as of now I haven't done anything related to design of eccentric cones.

1. The Angle of repose of the material to be stored in the vessel
The angle of repose or the critical angle of repose, of a granular material is the steepest angle of descent or dip relative to the horizontal plane to which a material can be piled without slumping. At this angle, the material on the slope face is on the verge of sliding.
To empty a vessel the angle of the cone must be the same or greater than the angle of repose.
2. The diameter of the vessel
Sometimes its possible to do all the right things and still get bad results
