Shock Evaluator 1.00a by Ghino di Tacco info at ghinoditacco@hotmail.com PabloSoft Research, inc. This application has been developed for the TI92+ calculator. For a DeLaval nozzle (Q1D model), it calculates: 1. exit density; 2. exit pressure; 3. exit temperature; 4. exit Mach number; 5. exit speed; 6. pressure at the exit section when no shock takes place in the nozzle (pusu); 7. isentropic exit pressures (plim,pad); 8. stagnation pressure after the shock (p02); 9. Mach no. before the shock (M2); 10. shock area (As/Amin). The input data are: 1. stagnation pressure of the reservoir: 2. either: a. exit pressure or b. exit temperature or c. exit density. Simply type Shockev(). Let it run (it takes less than 2 minutes): it might tell you that the input data are not compatible with a shock in the nozzle. The software is only in italian at the moment. Thanks for suggesting me possible improvements and bugs. Please report bugs at: ghinoditacco@hotmail.com
