Definition of carbon market. A market that is created from the trading of carbon emission allowances to encourage or help countries and companies to limit their carbon dioxide (CO2) emissions. This is also known as emissions or carbon trading. Carbon emissions trading is a way of reducing greenhouse gases produced by polluters.
In a convergent nozzle, there is an increase in velocity and a decrease in pressure, but we know that pressure is inversely proportional to area. Then why is this pressure decreased in convergent nozzle, although there is a decrease in area? The pressure drops in a convergent nozzle because of the Bernoulli Principle. A nozzle is a spout on the end of a hose or pipe used to control the movement of a fluid like water or air. A convergent nozzle is a nozzle that starts big and gets smaller-a decrease in cross-sectional area. As a fluid enters the smaller cross-section, it has to speed up due to the conservation of mass.
This amount of pressure is called one atmosphere of pressure because it is the amount of pressure the earth's atmosphere exerts. Most pressure measurements in scuba diving are given in units of atmospheres or ATA. â¢ Pressure Increases With Depth. The weight of the water above a diver exerts pressure on his body. The deeper a diver descends, the more water he has above him, and the more pressure it exerts on his body. The pressure a diver experiences at a certain depth is the sum of all the pressures above him, both from the water and the air. â¢ every 33 feet of salt water = 1 ATA of pressure.
