22 [2] Problem statement: A vertical tube open to the atmosphere is connected to the vein in the arm of a person Determine the height (h) that the blood rises in the tube. Schematic outline: Bloed 0.17 Assumptions/Approximation: 1. The density of blood is constant 2. The gage pressure of blood is 120 mm Hg (mercury Physical laws -pg dp d: Properties The densities of blood and well as 100 Department of Chem ChE 204 - Process Fluid Mechanics Semester: Student Outcomes: (1) Instructor: Dr. Sayeed Rushd Quiz No.: 1 Date: If you make any assumption, please state that clearly Q1. [2] Problem statement: As a process engineer, you have been assigned the job to estimate (1) the force and (2) the shear stress necessary to drag a 1 mx 1 m flat plate on a floor covered with a viscous lubricant (4 - 6 mPa.s). Prior to the estimation, you checked the lubricated floor to find the maximum and minimum thickness of the lubricant layer as 1.0 mm and 0.1 mm, respectively. a) Which values for the force (F) and the shear stress (6) would you suggest to your manager and why? Assume a reasonable value for the velocity (V). b) Draw the velocity profile. Schematic outline: V(m/s) Lubricant Flat plate F (N) Floor F = MY A Assumptions/Approximations: Physical laws: F
