It is also noted that the Hall long pitot tube can be inserted I through a corporation cock. If you would like to make some further investigation in regard to this equipment, and, if ay understanding is correct, it would be possible to Install corporation cocks in the various lines as indi­cated on attached rough sketch dated June 4, 1953* as measure­ments were made, this measuring equipment could be carried from on©
