LUNG CAPACITY Lung capacities are combinations of specific lung volumes. The lung capacities are measurements of two or more volumes. The total lung capacity (TLC) is a measurement of the total amount of air that the lung can hold; normally it is 6 litters for adult male and 4.2 litters for an adult female. The vital capacity (VC) measures the maximum amount of air that can be inhaled or exhaled during a respiratory cycle. The Residual Volume (RV) is the amount of gas remaining the lungs after a

and functional residual capacity (FRC) play a very important role to ensure the constancy of alveolar gas tensions. Firstly it is important to understand what the anatomical dead space and FRC actually are. The anatomical dead space refers to the gas in the conducting areas of the respiratory system where air does not come into contact with alveoli. Examples of places in the respiratory system where anatomical dead space is present are the mouth and trachea. The functional residual capacity is the

measurement of lung volumes and capacities. Results from this particular experiment may deviate from the predicted values obtained using the Goldman and Becklake equations for Pulmonary function if the individual tested has a habit of smoking which could lead to a drop in functional residual capacity. The natural recoil of the lung is also evident in figure 1. During natural inspiration‚ the volume of air increases in an exponential manner until it reaches the inspiratory reserve volume.

Our lungs have a greater capacity than we use when we take a normal breath. Scientists use various terms to describe the different components of lung capacity. Tidal Volume is the amount of air breathed out in a single normal breath (inhalation and exhalation). The Inspiratory Reserve Volume is the amount of air you can inhale over

In the 1880 through the 1930 “greater affluence led to new economic opportunities and a larger and greater political stability in most countries‚ but the dependence upon exports also made Latin America subject to global economic forces over which it had no control.” (A Concise Introduction to Latin American Politics and Development P. 8) An example of this would

INFLUENCE OF RESIDUAL STRESSES ON FATIGUE FAILURE OF BUTT WELDED STAINLESS STEEL PIPE Areef A Department of Mechanical Engineering Chendhuran college of Engineering and technology Pudhukkottai‚ Tamilnadu areefabdulrahman@gmail.com Abstract— This project is aimed to understand the influence of residual stresses on the fatigue failure of butt welded stainless steel pipe joints. In order to carry out this study it requires an experimental fatigue failure data and a computer aided analysis of these

of mass and volume. The ratio of the mass per unit volume is density‚ d and is written as (D = m/v). Using the metric system‚ the ratio for solids and liquids is expressed in g/mL or g/cm. Matter expands and contracts according to temperature. For liquids and solids‚ the change in volume is very small‚ but for gases‚ a temperature results in a proportional change in the volume. Therefore‚ gas density is dependent upon temperature; for liquids and solids‚ the small effect on volume is often ignored
