How I do my job better drinking bird happy? My happy drinking bird is very slow. How can I make my happy drinking bird drinking water in the glass faster. I try to adjust the bird and it gets worse.
The drinking bird is basically a heat engine that exploits a temperature differential to convert heat energy into kinetic energy and perform mechanical work. Like all heat engines, the drinking bird operates through a thermodynamic cycle. The initial state of the system is a bird with a wet head oriented vertically with an initial oscillation on its pivot.
The cycle works as follows:
The water evaporates from the head (Maxwell-Boltzmann distribution)
Evaporation lowers the temperature of the glass head (heat of vaporization)
The temperature drop causes a portion of dichloromethane vapors in the head to condense
The lowest temperature and condensation and the cause of the downward pressure of the head (ideal gas law)
The pressure differential between the head and base causes the liquid to be pushed from the base.
As the liquid flow in the head, the bird becomes top heavy and over during its oscillations.
When the bird tips over, the lower end of the neck tube rises above the liquid surface.
A steam bubble rises in the tube liquid moving through this space, as will
Liquid flows back into the lower bowl, and the vapor pressure equalizes between the top and bottom of the bulbs
The weight of the liquid in the bottom bulb restores the bird in its vertical position
If a glass of water is placed so that the beak dips into it on its descent, the bird will continue to absorb water and the cycle will continue as long as there is enough water in the glass keep your head wet. However, the bird will continue to dive without a water source, while the head is wet, or as long as a temperature differential is maintained between the head and body. This difference can be generated without evaporative cooling in the head - such as a heat source directed at the bottom of the bulb will create a pressure differential between the top and bottom will be the prime mover. The ultimate source of energy is heat in the environment - the toy is not a perpetual motion machine.
Therefore, you can not go faster. You can maybe try to warm temperate.
