What else can I help you with?
When 2 shafts are parallel to each other at a certain distance and no gears or belts are to be used then what is the coupling to be used to transmit the motion between the shafts?
Air or fluid pressure... If you put cylinders in the shafts and connect them through pipes or tubes, then you can transfer pneumatic or hydraulic pressure form one to the other. As one cylinder is lowered in one shaft, it will displace the fluid (air being a fluid) and because that fluid would have no escape, it would force the cylinder in the other shaft to rise.
How does turbine work?
Steam or water, it works the reverse of a fan, where the fan pushes air down, the turbine is turned by the steam or water. there's a shaft leading from the turbine to the generator, which produces the electricity
How do air get in to hydronic heating system?
True hydronic baseboard heat has an opening at both the top and the bottom of the wall unit with a finned copper tube running down its length. Because hot air is less dense than cold air, the hot air naturally rises. As heat is absorbed in the air surrounding the finned copper tube, it rises and flows out of the opening at the top. (convection) As this warm air leaves the heater it draws cooler air into the bottom opening which is then heated and flows out the top continuously as long as there is heat in the finned copper tube.
Which is the name for the bits of ash and dust put into the air by certain kinds of diesel engines?
particulates.
What is the function of the propeller?
The propellers purpose is to pull (or push) the aircraft forward through the air. It does this in much the same way that the airplanes wing produces lift, only instead of being pushed forward through the air, it is spun in circles through the air.Most modern airplanes have a variable-pitch (fixed speed) propeller. The pilot is able to adjust the pitch (or bite) of the propeller to maximize performance at various altitudes.A propeller is a type of fan that converts rotational motion into thrust by transmitting power. The shape and angle of the blade create pressure.
How many miners got out of the Knox mine disaster through the eagle air shaft?
My research concluded that, thanks to the knowledge of the Eagle Air Shaft by mine surveyor Joe Stella, 33 miners were able to escape through it.
What is some mining equipment for shaft mining?
Shaft mining is the earnest form of underground mining. Underground mining is selected when the rock or mineral is so far to reach using surface mining. Shaft mining is the kind of mine that you normally see in movies where the miner travels straight down into a profound, dark tunnel until he reaches the base. The shaft mine has a vertical man shaft, a tunnel where the men travel up and down in an elevator. Equipment is taken into the mine using this shaft, too. Short tunnels to the ore are dug from that man shaft. When the ore is dynamited and broken into chunks, it is taken to the top and loaded into trucks through a second shaft. There is usually an air shaft that gives the mine ventilation. When we visited a coal mine, it was amazing how much air moved around in the tunnels. Moving air removes the gases that occur naturally underground.
What would happen to the air pressure if you took a barometer from a mountain top down into a mine shaft?
the atmospheric pressure on top of a moutain would be lower than the atmospheric pressure down in a mine shaft
What changes in air pressure what would you expect if you carried a barometer down a mine shaft?
Density and air pressure will increase, while altitude decreases.

Why do miners light a fire beneath a shaft?
Miners light a fire beneath a shaft to create an updraft that helps circulate fresh air into the mine. This improves ventilation for the miners working underground by pulling out stale air and harmful gases.
What chages in air pressure would you expect if your carried a baromether down a mine shaft?
Pressure would increase as you went downward.
What is an air shaft?
An air shaft is a vertical shaft which supplies ventilation to a tunnel or underground facility.
How does the density of air in a deep mine compare with the air density at the earth's surface?
Air is compressible (i.e. when you squish it it gets denser). This means that the air at the top of the atmosphere is less dense than the air lower down in the atmosphere because the weight of the air above squishes the air below it. If you go up in a lift in a tall building, your ears 'pop' because the air at the top is less dense than the air was at the bottom. As you go down a mine there is more air above you than at the top of the mine shaft so the air gets progressively denser the deeper you go. At the bottom of the mine the air is, therefore, more dense than at the earth's surface.
What happens if you bring a barometer down a mine?
As you bring a barometer down a mine, the atmospheric pressure increases because of the weight of the air above pushing down. This causes the barometer to indicate a higher pressure reading compared to the surface. This increase in pressure can be used to estimate the depth of the mine shaft.
Why is no air coming out of your vents but you can hear the fan blower running in your 1994 Acura Legend?
2 problems: Either the fan broke loose from the blower motor shaft or there is debris (usually leaves or pine needles) blocking the air entry way.
