Viscometry & Hemorheology Lab Report

Viscometry & Hemorheology Lab Report

Description

 

 

One combined Lab Report . Given the two reports combined into one, you need a FULL Introduction; full Materials & Methods; Results – please group into separate analyses for viscometry & hemorheology; Discussion – please write two distinct sections discussing your viscometry findings separately from your hemorheology findings; Conclusions – give two distinct paragraphs or more describing the overall findings in the two labs.

i will post the file need for each lab

for viscometry

PLEASE see the attached Excel data files that my Prof collected for water & two different concentrations of chocolate sauce. The # signs in the data lists mean that the viscometer could not calculate a shear stress measurement at that speed because the fluid was too viscous. If your data do not follow a noticeable trend, you can use prof data to comment on the differences with yours.

See attached files for descriptions on Viscometry & Viscosity.

Here is a description of a T-test & its p-value.

for Hemorhelogy

Please see prof attached data as a back-up for some decent data from the hemorheology measurements.

His files are named with a 0 to represent plasma. The .5 in the file name represents 0.5 x hematocrit data. The 1 in the file name means regular blood. And the 1.5 in the filename means 1.5 x hematocrit. His spindle speeds from these data go from 12 – 80 rpms.

i post envying thing u need let me know if u have any question

Viscosity Notes From the Physics Hypertextbook https://physics.info/viscosity/ Discussion definitions Informally, viscosity is the quantity that describes a fluid’s resistance to flow. Fluids resist the relative motion of immersed objects through them as well as to the motion of layers with differing velocities within them. Formally, viscosity (represented by the symbol η “eta”) is the ratio of the shearing stress (ƒ/A) to the velocity gradient (Δvx/Δz or dvx/dz) in a fluid. ⎛F⎞ ⎛Δvx⎞ η =⎝ ⎠÷⎝ ⎠ A Δz ⎛ ƒ ⎞ ⎛dvx⎞ η =⎝ ⎠÷⎝ ⎠ A dz or The more usual form of this relationship, called Newton’s equation, states that the resulting shear of a fluid is directly proportional to the force applied and inversely proportional to its viscosity. The similarity to Newton’s second law of motion (ƒ = ma) should be apparent. F Δvx =η A Δz or ⇕ F=m ƒ dvx =η A dz ⇕ Δv Δt or ƒ =m dv dt The SI unit of
