Oil (SG = 0.89) enters at section 1 in Fig. P3.20 at a weight flow of 250 N/h to lubricate a thrust bearing. The steady oil flow exits radially through the narrow clearance between thrust plates (D=10 cm, h=2 mm, D1=3 mm). Compute (a) the outlet volume flux in mL/s and (b) the average outlet velocity in cm/s.
