Nozzle design

[HOUARI YAHIAOUI]

HELLO;
You will find in attached the picture of nozzle with details in question.
Please help me to find out with my issue; my questions are :
1) What’s the formula utilized to find the value of L=318,9 mm, and what “L” represent in this figure??
2) I find in the report of COMPRESS that the Lpr=348.85 mm, what’s the difference between L and Lpr?
3) How they calculate h=197.1 mm? as I understand is the length of the hub of nozzle.

my salutations

The problem with sloppy work is that the supply FAR EXCEEDS the demand
