      Putting the equation whivi= whfvf Where w = width hi = initial thichness hf = final thickness Vi= entry velocity Vf= exit velocity Exit velocity is 16.66 cm/s

      Putting the equation whivi= whfvf
      Where w = width
      hi = initial thichness
      hf = final thickness
      Vi= entry velocity
      Vf= exit velocity
      Exit velocity is 16.66 cm/s
