Task 5
A non-Newtonian fluid is a fluid with properties that differ in any way from those of Newtonian
fluids. Most commonly, the viscosity of non-Newtonian fluids is dependent on shear rate or
shear rate history. Some non-Newtonian fluids with shear-inde
fluid flow
In fluid flow, it is a common problem to calculate the pressure drop in an established piping
network.[4] Once the friction factor, f, is known, it becomes easier to handle different pipeflow problems, viz. calculating the pressure drop for eva
Dilatant
Unlike rheopectic and thixotropic non-Newtonian fluids, those described as dilatant will
change their viscosity dependent on how much force applied is, not how long for. The harder
you hit a dilatant fluid the more viscous it becomes. One such ex

Task 1
A digital multi-meter can be used to measure resistance, voltage and current of a
circuit. The first step to use a digital multi-meter is to turn the meter on and then
insert the probes into the correct connect
temperature dependence of liquid viscosity
The temperature dependence of liquid viscosity is the phenomenon by which liquid viscosity
tends to decrease (or, alternatively, its fluidity tends to increase) as its temperature
increases. This can be observed,
