Consider a bentonitic mudflow with density 1100 kg/m3 and dynamic viscosity 2 pa-s.
a. what is the approximate fraction of mud in the mixture?
b. how much more viscous is this mud than water? why would adding bentonite to water increase its viscosity so much? do you think another material (e. g. silica or carbonate silt) would have the same effect?
c. if the mud is flowing steadily on a slope of 0.001 at a depth of 1 m in a channel 50 m wide, find the unit discharge, the total discharge (volume of fluid/time), the average flow velocity, and the maximum flow velocity.
d. if the mudflow is 500 m wide, how long will it take to deliver a million (106) m3 of mud?

Ithink d hope that

The answer is:   [d]:   "ultraviolet" {"  uv  "} .

In order to improve results, many different steps can be taken into account. 1) using more precise scales and thermometers is always something that should be considered as being precise means that you are more exact with your answer.2) increasing the sample size should also be considered, if you have a bigger sample size you are able to determine if your results are accurate as well as if there are any variables that should be taken into account plus it assists in the statistical analysis and produces overall better data3) using better handwriting is also a plus, along with organizing the data properly so that others are also able to read the results and even redo the experiment in the future if it is needed.
