You are help to educate a patient on the ramifications of a partial arterial blockage you have recently discovered. To communicate the severity, you decide to tell the patient about how much of the volume of blood that normally passes through the artery has decreased. The relationship you are describing is called AV Poiseuille's equation and it reads: ™R^ (P₁-P₂) 8nl If the At radius of the artery decreases by a factor of 2 because of the blockage (as shown in the image below), by what factor has the volume flow rate (A) decreased?

In studying sand transport by ocean waves, A. Shields in 1936 postulated that the bottom shear stress τ required to move particles depends upon gravity g, particle size d and density ρp, and water density ρ and viscosity μ. Express this relationship in dimensionless form using the first principle (dimensional analysis).

Under certain conditions, wind blowing past a rectangular speed limit sign can cause the sign to oscillate with a frequency w. (See the figure below and the Video.) Assume that w is a function of the sign width, b, sign height, h, wind velocity, V, air density, p, and an elastic constant, k, for the supporting pole. The constant, k, has dimensions of FL.
