high velocity doesnt neccearly mean high pressure ,and velicoty is impossible to decrease pressure ,because ,what drops the pressure is a sudden drop in pipe structure ,not in presure ,a sudden change on the ongoing fluid which mostly vapor ,vapor means in the vapor phase ,not boiling phase ,but vapor ,thats why theh call it vapor pressure ,not boiling pressure
i think velocity is not what drips the pressure is created from the physical structure if the pipe ,and how gasses behave ,its similar to the expansion valve because its very similar ,because both systems qre dealibg with fluids and high pressure and low preseure ,i call it narrower locatoin ,vecause the physical structure of the piipe the allowed the pressure to drop ,not because velocity decreses pressure ,pressure is related to temp ,the higher the temp the higher ,why the higher because when gas is heated it needs more spqce to hold it but when you icreases it in a cylinder without heat sourve of coursr ,its always must be cold ,and here is the paradox ,because if u apply heat and pressure simlultaneously ,u can apply pressure and cold to a closed system ,thank you God ,or if u want colder ,u can start with co2 as a refregerant ,but a comoressor to commpress co2 must be strong without external intervention ,on default or factory settings ,the next cycle will be colder depending on what gas is found on the second refr unit because there is heqt exchange happens between the 2 systems and when this happens ,the 2 unit cold end could get u to 170
How can I get a PDF of the designer book that contains the specialization of process and instrumentation? Do you have institutes that teach the designer stage? By the way, the explanation is more than excellent.
before this video i was completely blind about the differences between these two. but you clarify it very simply and perfect. thank you very much! you are amazing <33
