77                                       Probably will not solve if velocity is sonic at 1. Once the normal solution method fails, the program solves
78                                       by setting Vel 1 at sonic flow and calculating P1. This amounts to resetting flowrate also. P2 is kept constant.
79                                       A lower flow is generally selected. If you still want the original flow calculated, you should change to
80                                       specifying Ncalc=2 and setting flow. Program will calculate P1 required (sonic conditions).

                                         Calculates downstream pressure given upstream pressure and flowrate. If downstream velocity exceeds
83                                       sonic the downstream pressure is reset. If inlet velocity exceeds sonic, the inlet pressure is reset to be high
84                                       enough so that the inlet conditions are sonic. If dia(1) = dia(2) this will obviously not solve anything and
85                                       the program will not solve. The user then will have to take appropriate action to reset the mass flow rate.
