We have a 500 litre tank containing a liquid product contaminated by small particles that must be removed before the product can be sold. the particle concentration is, initially, 10' particles/m and the product may only be sold if the particle concentration is reduced to 10 particles/m. we have a filter that will effectively remove all particles from the liquid product. (a) at what rate must the product be pumped through the filter to make the product acceptable after 2 days; you may assume that the tank is well- mixed and the filtered product is continuously returned to tank. draw a sketch of this process (b) at the pumping rate determined in part (a) how long will it take to filter the product if a second vessel is used to hold the filtrate. what will the particle concentration in the filtered product be in this case? (c) repeat part (a) assuming the filter only removes 90% of the particles on each pass.

Electromagnets coils of wire paper clips picked up 10 3 15 6 20 9 25 12 ms. owens' class was studying magnets. ms. owens showed her students how to make an electromagnet using a nail, a d-cell battery, and plastic coated wire. the students wrapped the wire around the nail and then attached the ends to the battery. when they were finished, they tested their magnets by investigating how many paperclips their magnets could pick up. they also tested whether they could increase the strength of their electromagnets by using more coils of wire. they recorded the class average of their results in the data table seen here. ms. owens asked her students to graph their data in a line graph. how should the students label the x-axis on their line graph? a) size of battery b) number of paper clips c) number of coils of wire d) strength of electromagnet
