Answer 1

your answer is correct

According to on y self, your calculation is correct. B = 0.012 ft dP = 100 P_sf/ft mu = 10^-3 16 f.s/ft^2 SG = 0.80 V_max = B^3 r/12 mu middot dh/dz dh/dz = d (P/r + z)/dz = dP/z/dz + -dz/dz = -1 V_max = 0.012 ft^3 (r) (-1)/12 times 10^-3 (1b f.s/ft^2) ft [r = 25,760 1b f/ft^3 V_max = 0.012 ft^3 (25760 1b f/ft^3)/0.012 1b f.s/ft = 3.70944 ft/s
