===========================================================================

A floating object experiences two different types of forces. One is the familiar gravitational force. Gravitational force is proportional to the mass of the object. It acts downward.

Gravitational force = mg = V d g, where

V = Volume of the object
d = Density of the object
g = Acceleration of gravity ...

Solution Summary

Forces on an immersed object and the relation ship of the immersed volume to the densities of the object and the fluid are discussed in detail using diagrams and equations in this 3-page word document. I have run the simulation to collect data. The data is presented in the form a graph as well.

A body falling in a relatively dense fluid, oil for example, is acted on by three forces: the weight W due to gravity (acting downwards), a resistence force R and a bouyant force B (both actin upwards). The wieght W of the object of mass m is mg. The bouyant force B is equal to the weight of the fluid displaced by the object.

Consider an object with height h, mass M, and uniform cross sectional area A floating upright in a liquid with density p.
a.) Calculate the vertical distance from the surface of the liquid to the bottom of the floating object at equilibrium.
b.) A downward force of magnitude F is applied to the top of the object. At the

Derive from first principles the Poiseuille equation for pressure drop generated by the steady flow of a Newtonian fluid through a straight tube of circular cross-section. If the flow is laminar, what is the form of the velocity profile with in the tube? Show that the mean velocity is half the peak in such circumstances.

Please help with the given problem:
It seems that simulation could handle any situation or study. But is that always true? Discuss instances in which a simulation would be important and useful, and then a situation in which a simulation would not be appropriate. Finally, include a set of rules you would use to determine if

For laminar flow in the entrance of to a pipe, as shown in figure, the entrance is uniform u=U0, and the flow downstream is parabolic in profileu(r)=C(r0^2-r^2). Using integrla relations, show that the viscous drag exerted on the pipe walls between 0 and x is...
