If air is blown through the larger end of a cone how do you calculate what the pressure of the air exiting the smaller end will be?

You'll use these two equations:
Ideal Gas Law: P=pRT
(where P=pressure, p=density, R=gas constant, T=temperature)
and also conservation of mass/energy principle:
sum of mass flow rate in=sum of mass flow rate out
and since
m=pvA
(where m=mass flow rate, p=density, v=velocity, and A=cross-sectional area) you can write
pvA(in)=pvA(out)
Using these 2 equations you should be able to solve the problem.

What happens when two different radius bubbles are connected by a hollow tube?
The larger bubble has a larger diameter and therefore less pressure than the smaller bubble since: p(in) = p(out) + 2y/r. p = pressure y = surface tension r = radius Therefore, pressure is inversely proportionate to the radius size. Since the smaller bubble has a smaller radius, and therefore, a greater internal pressure, it would "push" the air through the hollow tube to the larger one until the smaller one ceases to exist.
What is the difference between refracted light and reflected light?
Refraction is the change in direction caused by a speed differential as light travels through different mediums, or temperature/pressure gradients. Reflection is light directly hitting an object and exiting at the same angle at which it hit.
How do you calculate satic pressure?
Consists of the pressure the air exerts in the direction of flow (Velocity Pressure) plus the pressure air exerts perpendicular to the plenum or container through which the air moves. (static pressure) In other words: PT = PV + PS PT = Total Pressure PV = Velocity Pressure PS = Static Pressure http://www.refrigeration-engineer.com/forums/archive/index.php/t-14342.html
Why does a sharp axe cut through wood more easily than a blunt one?
Because the cutting edge has a smaller area when the blade is sharp so the pressure it can exert increased
How do you get area given pressure and velocity?
Velocity is not involved in the definition of pressure, so knowing it doesn't help you calculate pressure. Pressure = force/area You may be talking about wind pressure, which obviously does depend on the speed of the wind, or on the speed of the object through quiet air. In order to know the wind force, you have to know the specific size, shape, dimensions, and surface texture of the object past which the air is moving.
Why is the pressure in arteries much greater than in veins?
Because the arteries have smaller bore than veins. Through smaller cross sectional area blood flows with greater pressure.

Where does the freon get added in a 1999 300m Chrysler?
It gets added through the low pressure service port. It is the smaller of the two ports.

How do you calculate the amount of gas required to raise the pressure of a closed vessel to a known value?
If you know the temperature, pressure and volume of the vessel, you can calculate the amount of moles through the Ideal gas law. PV = nRT That is assuming you have ideal conditions. If not, a variance of the ideal gas law can be used in order to get the moles of your gas.
What would cause the water in the reservoir tank of a 1997 Pontiac Grand AM SE 4-cylinder to instantly rumble and boil after starting?
Excess pressure is building up in the radiator probably from a blown head gasket and is exiting through the radiator cap and into the overflow bottle.
Why do veins have low blood pressure?
Fish have one circuit and two heart chambers in their circulatory system. Blood collects in the atrium and moves to the ventricle where it is pumped first to the gills to collect oxygen, then to the body to deliver the oxygen to tissues. Since the blood does not return to the heart after moving through the gills, it has low pressure as it moves through the body.
