Consider two solid spheres P and Q each of density
8 gm cm3 and diameters 1 cm and 0.5 cm, respectively.
Sphere P is dropped into a liquid of density 0.8 gm cm
cm 3 and
viscosity n = 3 poiseulles. Sphere Q is dropped into a liquid of
density 1.6 gm cm3 and viscosity n = 2 poiseulles. The ratio
of the terminal velocities of P and Q is

Drag Force: A spherical particle of radius 5.9 cm and a mass of 226 g is moving through a fluid of the same density. (This means you can ignore the effects of gravity.) The position of the particle is given by x (t) 1 In (1+ bvot), where x is its position and t is the elapsed time. The initial speed vo is 27.8 m/s, and the constant b is 0.3 m-1. (b) What is the velocity of the particle after 3.3 seconds? (c) What is the acceleration of the particle after 3.3 seconds?
A probe on a dwarf planet collects 5 moles [mol] of dust material. The sample, which completely fills a cube with a side length of 4 centimeter [cm], weighs 0.19 newtons [N] on the dwarf planet. The density of the material is determined to be 3160 grams per liter [g/L].Determine the gravity of the dwarf planet in units of meters per seconds squared [m/s2].
A smoking room is to accommodate 50 smokers. The fresh air requirement for smoking areas is specified to be 40 L/s per person. The air velocity in the ventilation duct is 8 m/s. Determine: b) The diameter of the ventilation duct in [cm] SOLUTION
While workers spray paint the ceiling of a room, numerous small paint aerosols are dispersed into the air. Eventually, these particles will settle out and fall to the floor or other surfaces. Consider small spherical paint particles of diameter D = 10 μm and specific gravity of 1.2. Determine the time it would take this particle to fall 2.4 m from near the ceiling to the floor. Assume that the air within the room is motionless.
You are with an excursion party on an exploration of the surface of Mars. You find a small lake of water of that 1.76 m. Assume the density of the freshwater is unchanged on Mars. You measure the absolute pressure at the bottom of the lake to be one 161,800 Pa. What is the absolute pressure (in atm) at the surface of the lake. Assume the value of G on Mars is 3.72 m/s^2

The aorta carries blood away from the heart and eventually branches into a large number of capillaries that distribute the blood to various body organs. If for an average person, the aorta has a radius of 1.2 cm and blood travels through it at a speed of 45 cm/s and the capillaries have an average radius of 5.0 x 104 cm and blood travels through them at a speed of 0.005 cm/s, determine the approximate number of capillaries in the human body. capillaries Vinuing Sound Work Bovert to I Rocponco
