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?

i think its 100.

hope this !

a. the law of proportion states the combination of 2 atoms in a specific ratio to produce multiple compounds such as the given statement of question ‘1st compound contains 88.8 % cu ’ indicates 88.8 g of cu is present along with 11.2 g oxygen in 100 g of compound whereas the statement ‘2st compound contains 79.9 % cu ’ indicates 79.9 g of cu is present along with 20.1 g oxygen in 100 g of compound

1st compound contains 88.8 g cu

for cu

m = 63 g /mol

atomic % = 88.8 /63 = 1.42

for o

m = 16 g /mol

atomic % = 11.2 /16 = 0.7

b. the emperical formula of 1st compound is

cu1.4o0.7

ca has a crystalline lattice with positive ions (since it is a metal, metals are positively charged) and electrons flow freely in its structure since the ca atoms have a large nuclear radius so the electrons are not tightly held, therefore the electrons can flow freely since they are not being highly attracted by the nucleus. moreover, one of the properties of metals are that they are conductors of electricity, thus proving ca is the element.
