Re: Μηχανική των Ρευστών (2011-12)
Στους υπερχειλιστές όταν χρησιμοποιώ τους τύπους σελίδας 165 στις σημειώσεις του κ. Κατσαρέλη έχω π.χ. h1=A3/0,75 και h2=A3/(μ*(h1)^(2/3))?? Γιατί έχω κάνει άπειρες φορές την πράξη και το h2 δε μου δίνει w2 λογικό νούμερο (σε σχέση με το w1). Εφαρμόζω σίγουρα σωστά τον τύπο;;;;

Re: Μηχανική των Ρευστών (2011-12)
ο σωστός τύπος είναι : h2=A3/(μ(h1)^(2/3)) δηλ. μ του h1 και όχι μ*(h1)!
Re: Μηχανική των Ρευστών (2011-12)
Οταν λεει μ(h1)^(2/3) εννοεί το μ για h=h1 στον τυπο toυ μ ενω εγω αντικαθιστουσα μ1*h1^(2/3)... Για να μην τα πολυλογω ειναι Α3/(μ^(2/3)) σκετα!
