The reynolds number, re, is a dimensionless number used to characterize different flow regimes in a fluid. the reynolds number can be defined as dvp re= where d is the diameter of the pipe, vis the mean fluid velocity, pis the density of the fluid, and pis the dynamic viscosity of the fluid. what is the reynolds number of blood leaving the heart through the aorta if it has a dynamic viscosity of u 3.40 cp (centipoise), a density of p 1043 kg/m, travels at a mean fluid velocity of v= 32.9 cm/s, and the diameter of the aorta is d = 1.85 cm?

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
