Shock compression target numbers
  • Shock compression target numbers - Woods thru SX                                       vdb / excel / shc_target_numbers.xls
    • Woods at lower end.  MX around aver.  SX at upper end.
    • Pressure testing breaks down the forces into: comp force, cadj force, drag force and gas force.
    • HOWEVER, for shc target nu series, we only list oall comp force.  The cadj force is based on keeping P.r about 10% above P.ca at 50ips (via Susanto excel).      
    • 10.2 range:        2.7    /     3.0      /   3.5
    • 50.10 range:      3.3   /      3.6     /    3.9
                     less prog   / mid prog /  more prog
                       more ls  /   mid ls   /  less ls
