Gaseous exchange is a natural process, ventilation is a forced process.
A cavitation plate is the adjustable metal plate that runs along the bottom of the transom on a V-drive. Some people call the flat metal plate on an outboard or outdrive a cavitation plate but the correct name is anti ventilation plate and cavitation and ventillation are not the same. It is similar in function to Trim Tabs. A cavitation plate is used to adjust the trim of a V-Drive and keep the nose on the water. Here is a link to a picture on PerformanceBoats dot com In this picture of a V-drive, the cavitation plate is anodized red.
CAVITATION is the process of formation of vapour bubbles of flowing fluid in a region where the pressure of the liquid falls below its vapour pressure and the sudden collapsing of these vapour bubbles in region of high pressure. where SUPERCAVITATION IS THE CONTROLLED FORM OF CAVITATION WHICH HELP US TO attain more underwater speed
breathing is when you can breath yourself without the help of anything however ventilation is when you need the help of something to breath.....
A pit is open, whereas a mine has a ventilation circuit.
External respiration, the process by which gases are exchanged between the atmosphere and the pulmonary loop of circulationWhereas,Internal respiration: the is the gaseous exchange between the blood and tissue ( and also cells)
respiration is the process of yainhaling oxygen to the body and provide the cells.
Exhaust fan is only use for exhaust the old air, while ventilation fan is use for both purpose intake and exhaust.
The cavitaion index across a valve or pipe fitting is defined as the ratio of difference between upstream pressure and vapor pressure to the pressure drop across the valve or fitting. The index at which incipient cavitation, damage, or choked flow occurs is based on testing and depends on the type of valve or fitting.
There are 30 chest compressions between ventilation's for 1-rescuer CPR.
Emerson Cavitation Tunnel was created in 1949.
