What is the diameter of HIV?
What is the length of a mitochondrion?
What are the units of heat capacity?
What is the diameter of a water molecule?
What is the diameter of a hemoglobin molecule?
An artery of diameter a contains blood flowing at speed v. At some point along its length, this artery splits into two smaller arteries, each with a diameter a/2. In terms of v and a, what is the velocity of the blood in the smaller arteries?
What are the units of specific heat capacity?
What is the length of an E.coli bacterium?
What is the diameter of a red blood cell?
Do bacteria swim in water at high Reynolds number or low Reynolds number?
Low Reynolds number
Explain what the "no slip" boundary condition means.
The speed of flow tangential to a surface is zero at the surface. In other words, the fluid "sticks" to the surface.
Reynolds number equation
v / n
p = Density
l = Length
v = Velocity
Write a differential equation that governs y(t)
y(t)= a-y/t (t=squiggly t)
Solve the differential equation for y(t) in terms of a and squiggly t, assuming no drug is present at t=0
After a long time (t>>squiggly t), what is the steady-state amount of the drug in the body?
The factor P(E)=Ce^(−E/kT) that appears in Boltzmann's distribution law and in the Boltzmann occupation factor. [CPM.2; QPM.1]
