Solution Summary

An expression for drag coeffecients around a falling sphere is found. The solution is detailed and well presented. The solution received a rating of "5" from the student who posted the question.

We would like to know the nature of the drag forces experienced by a sphere as it passes through a fluid. The sphere has a low speed. Therefore, the drag force is highly dependent on the viscosity of the fluid. The fluid density is to be neglected.
a) Use dimensional analysis to develop a model for drag force: F (MLT^-2) as a

Find an equation of the largest sphere with center (10, 1 , 3) that is contained completely in the first octant.
= 0
Note that you must move everything to the left hand side of the equation that we desire the coefficients of the quadratic terms to be 1.

I have a problem I am unable to figure out, I keep using the hard-theory formula for "A" to get the rate constant, however the value I get seems way to small every time I try to do it. Can someone please help me with this problem? I posting the homework set its problem number 5, I keep getting (4.28x10^-29dm3/mol s) as "k" pleas

1. Find an equation for the terminal velocity of a sphere falling through a viscous fluid (like water or blood). How does the terminal velocity scale with the size of the falling object? Assume that the density of that object is much larger than that of the fluid through which it falls (neglect buoyancy).
a. V ~ L^-3
b. V ~

Show that the gravitational self-energy (energy of assembly piecewise from infinity) of a uniform sphere of mass M and radius R is:
U= -3/5 GM^2/R

Determine the specific gravity of spherical particles, D=(1/200 in), which drop through air at 33degrees F at a speed U of 0.3 ft/s. The drag force on a small sphere in laminar motion is given by 3(pi)(mu)DU.

A cube has a sphere inscribed inside of it. It has another sphere circumscribed on the outside ot if (it being the cube). What is the ratio of the volume of the inside sphere to the volume of the outside sphere?

The ski boat's jet propulsive system draws water in at point A (at the middle of the bottom of the boat) and expels it at B (at back of boat) at 80ft/s relative to the boat. Assume that the water drawn in enters with no horizontal velocity relative to the surrounding water. The maximum mass flow rate of water through the engin
