engineering recuitment HPCL Engineer Mock Test 2024 Production Engineering (Manufacturing) Metal Forming Rolling
In the rolling process, if Vr is the velocity of roll surface, V0 is the velocity of material at the entrance to the deformation zone and V1 is the velocity of material at the exit of the rolls, then the forward slip is
1
\(\frac{{{V_r}}}{{{V_1} - {V_r}}} \times 100\) percent
2
\(\frac{{{V_r}}}{{{V_r} - {V_0}}} \times 100\) percent
3
\(\frac{{{V_1} - {V_r}}}{{{V_r}}} \times 100\) percent
4
\(\frac{{{V_r} - {V_0}}}{{{V_r}}} \times 100\) percent
