An aqueous solution (specific gravity = 1.26) flows through a pipe with variable diameter. The following data is obtained from 2 points in the pipe. a. Assuming negligible friction, determine the linear velocity of the solution (m/s) at point 2. b. Determine the inner diameter of the pipe (cm) at point 1. point 1 point 2 Pgauge 162kPa 97kPa Linear Velocity 4.78m/s ? Height above sea level 14.23m 20.35m Inner diameter of pipe ? 6.25cm
