The pipe is in the form of a venturi it narrows in section and then widens again, causing the airflow to increase in speed in the narrowest part. Below the venturi is a butterfly valve called the throttle valve a rotating disc that can be turned end-on to the airflow, so as to hardly restrict the flow at all, or can be rotated so that it (almost) completely blocks the flow of air. This valve controls the flow of air through the carburetor throat and thus the quantity of air/fuel mixture the system will deliver, thereby regulating engine power and speed. The throttle is connected, usually through a cable or a mechanical linkage of rods and joints or rarely by pneumatic link, to the accelerator pedal on a car or the equivalent control on other vehicles or
The process of ventilation provides air into the alveoli of the lungs. This is where gas exchange occurs. Gases diffuse across the membrane between the alveoli and the capillaries into the bloodstream according to Fick’s law: the rate of diffusion of a gas tissue is proportional to the tissue area, difference in partial pressure and is inversely proportional to the thickness , i.e. oxygen passes into the blood from alveoli and carbon dioxide exits the blood into the alveoli. The atmosphere consists of oxygen, nitrogen and carbon dioxide as well as other gases.
The piston would then create a low pressure area below the throttle. concentrated at the edge of the throttle valve as the air passes the idle port Engine idle speed is set by two different adjustments. The amount of fuel is adjusted by the mixture adjustment screw at the idle port. The amount of air is adjusted by changing the throttle stop screw. Second-stage idling starts as the throttle valve opens.
Pressure changes in the lungs are delivered by varieties in lung volume, as per the opposite relationship between the volume and pressure of a gas portrayed by Boyle's law. The mechanics of ventilation are affected by the physical properties of the lungs. On first thought, no doubt the surface strain in the alveoli would make a pressure that would bring about little alveoli to collapse and discharge their air into larger alveoli. This
Gas Chromatography Principle: A sample to be analysed is injected into the chromatography instrument. The sample solution enters a gas stream which transports the sample into a separation tube which is also known as the column. Various components in the sample solution separated inside the column. GC has principles similar to fractional distillation. Both processes separate mixture based on boiling point.
In the secondary evaporator, the feed seawater 2 was heated up by the mixed steam from the steam ejector, where its temperature is raised from Tf to the evaporating temperature, Ts. The secondary steam from the secondary evaporator splits into two portions: the first part is condensed in the condenser, while the rest is entrained by the steam ejector, where it is compressed by primary steam to raise the pressure and temperature and then it is introduced into the secondary evaporator as the heat source and is completely condensed into liquid. A known mass of fresh water (Mp + Ms) is
The oxygen in the lungs spreads out into the blood and carbon dioxide in the blood spreads out into the lungs. Internal respiration is the gasesous exchange in the body tissues. in contrast to these physiological processes, ventilation or breathing is a mechanical process that takes in and takes out air in to the and out pf the lungs. It consists of 2 steps: inspiration and expiration. In human body respiratory system takes place at the same time but it’s practical to think as it includes number of steps.
Under her guidance, I learnt to prepare process sheets for different rocket engine components. During that time, my experience of using CAD software was enhanced. I successfully completed my In-plant project on ‘To Study and Analyse Different Cooling Techniques for Spacecraft Engines’. I was fortunate to have a glimpse of BrahMos missile
the output gases travels to the scrubber where they are cooled down by spraying distilled water from the top of the column , so the gases rise up due to its light density . By a help of a fan the gases are pulled from the scrubber to the absorber . there is a chemical in the absorber called as monoethanolamine it has a liquid nature. This chemical is used to absorb CO_2 only and according the high density of it it settled down while other gases goes out. The settled mixture at the bottom can be called as rich miya.
The airplane is now simply a machine to be fabricated. The precise design of each individual rib, spar, and section of skin now takes place. The size, number, and location of fasteners (rivets, welded joints, etc.) are determined. Manufacturing tools and jigs are designed.
