Once the friction coefficient, C/,, has been determined, the valve pressure ratio at choking, (p2/pt choke) may be calculated by substituting the critical throat pressure... [Pg.82]

The valve pressure ratio at choking for conditions at time zero may be calculated from equation (9.23) with its throat pressure ratio at critical pi/p = Ptdpx =... [Pg.84]

Hence the valve pressure ratio at choking may be calculated from the quadratic curve... [Pg.344]
