Work equation
Below I show the kinetic energy difference work equation in finite form.
Where
c = the absolute velocity of the fluid
u = the driving speed (for example, the driving speed of an impeller is equal to R)
w = relative velocity of the fluid
Considerations
To arrive at the equation of work due to differences in kinetic energy in finite form we must consider the vector relation obtained from the kinematics of relative motions which would be the following.
Note: This report is written in vector form. Let us remember that a vector quantity is a physical quantity characterized by a direction, a direction and an intensity. It is therefore described by a vector.
Where
c = the absolute velocity of a fluid
u = the drag speed
w = relative velocity of the fluid
Conclusions
The kinetic energy difference work equation in finite form is an equation that is very useful in the design or study of turbomachinery

Have you ever studied or designed a turbomachine?

Equazione del lavoro
Qui di seguito mostro l’equazione del lavoro alle differenze di energia cinetica in forma finita.
Dove
c = la velocità assoluta del fluido
u = la velocità di trascinamento (esempio velocità di trascinamento di una girante pare a R)
w = velocità relativa del fluido
Considerazioni
Per arrivare all’equazione del lavoro alle differenze di energia cinetica in forma finita dobbiamo considerare la relazione vettoriale ricavata dalla cinematica dei moti relativi che sarebbe la seguente.
Nota: questa relazione è redatta in forma vettoriale. Ricordiamo che una grandezza vettoriale è una grandezza fisica caratterizzata da una direzione, un verso e un'intensità. Essa viene perciò descritta tramite un vettore.
Dove
c = la velocità assoluta di un fluido
u = la velocità di trascinamento
w = velocità relativa del fluido
Conclusioni
L’equazione del lavoro alle differenze di energia cinetica in forma finita è un'equazione che risulta molto utile nella progettazione o nello studio delle turbomacchine
Domanda
Avete mai studiato o progettato una turbomacchina?
THE END
Most of the time, those formula that we always see that seems complicated and looks like it will be hard to understand, it is actually easy to understand if only we can actually calm down to understand them very thoroughly
There are formulas that are easy to understand, some that are understandable by taking time and calm and others that are very complex to understand. In my opinion we are in the middle here
Non ho progettato una turbomacchina, ma all'università ricordo di aver studiato qualcosa a riguardo.
Benissimo, quindi come minimo ho risvegliato qualche tuo ricordo a riguardo.
I remember been taught the vector quantity when I was in school then. Even though at first I didn't really take it with all might but at the end of the day I begin to see the work in ones life
Thanks for stopping by, Vectors are one of the things I learned first in physics courses
I am able to understand thanks be to how you were able to explain it in simpler form
Thank you for your kind words
L'ho sentito, ma non l'ho fatto.
Anch’io ho già studiato turbomacchine, ma non ne ho mai usata una nei progetti che ho eseguito
Even though at first I wasn't really understanding what it was about but I must say as time goes on I now actually understand fully what you wrote about..thank you for sharing this
Thanks for leaving a comment, I would like to become more clear in explaining these concepts
