Mühendislik Formülleri

formuller

 

1) Güç ve Tork:  a) P(kW)= [T (N-m) x N (rpm)]/9550

                           b) P(Hp)= [T (Lb-İn) x N (rpm)]/6300

                           c) b) P(Hp)= [T (kgf-cm) x N (rpm)]/71620

 

                            ;T : Tork

                              P: Güç

                              N: Devir

2) Pompa Motor Gücü:  P(kW)= [p (bar)xQ (Lt/dak)]/ [600 x η(%)]

                             P: Güç
                             Q: Pompa kapasitesi
                              p: Basınç
                              η: Verim

3) Döndürme Torku;  T=JM x α

                                  JM=(M/2) x R2

 

                              T: Tork (N-m)
                              M: Dönen cismin kütlesi (Kg)
                             JM: Dönme atalet kuvveti (Kg-m2)
                               α:Dönen cismin açısal ivmesi (rad/sn2)
                              R:Dönen cismin yarı çapı (m)
