B. Water flows around a vertical circular channel between radii R1 = 10 cm and R2 20 cm with a speed profile of Ve 10r in the radial coordinate system as shown. Find the pressure difference between R1 & R2, labeled AP12, at the four angular locations indicated (A, B, C, D; 0 = 0°, 90°, 180°, 270°). %3D RI C R2
