Essays on Air Flow

[Subject/Course] [Submission Date]

“Soffit’ (origin: suffixus) is derived from Latin language and literally means ‘to fix underneath’. However, in architectural field, the term is usually referred to “the material that bridges the space between the siding on a house and the roofline” (Ambrose, Harris, & Stone 235). While soffits are primarily used around the main roof of a building, they can also be used under any structure with a noticeable ceiling including stairs flight, porches, columns, etc. They can be manufactured using a number of materials such as wood, vinyl, steel, fiber cement, and aluminum. It needs to be mentioned ...

Introduction

This paper aims at evaluating concepts of alteration in homeostatic state, secondary to temporal variables. It analyses the case study of Brad, a 45-year old coal cutter who has held the job for 25 years. Brad is experiencing a chronic cough due to prolonged exposure to coal. Importantly, he has not been attending yearly checkups because he fears that his lung is “black.” The disease leads to fibrosis, reduced diffusing ability, and dilation of the small airways. In the final stage, the airways, alveoli, and pulmonary capillaries become damaged.

How the disease described in the case study creates incongruous between ventilation and perfusion

Chronic lung disease may induce mismatch in ventilation and perfusion ...

Introduction

Air stripping lacks an official academic definition, but a widely accepted definition within the field regards it as the transfer of contaminants from aqueous solutions to air [1]. This process is commonly performed to decontaminate waste water and groundwater for public health purposes, given its ample use in the removal of volatile organic compounds (VOCs) from water into air. Air strippers, the devices that carry out this process, are composed of a cylindrical tank which can contain different materials such as steel, ceramic or plastic. Contaminated water is pumped into the apparatus through its upper inlet, proceeds ...

Roofing Ventilation

The need for ventilation in roofs and attics became apparent after it was observed that moisture inside attics, caused by the phenomenon of condensation, was deteriorating a large portion of the roofing materials and in extreme cases the insulation of the ceiling. Adding to this grief, wet attics became the breeding place for a variety of fungi and moulds . From then, wet attics had become the nightmare of many house owners. If roofing ventilations were a fancy contraption in the early days, in the modern world they are an integral part of any roofing solution. And gladly, there are ...

Introduction A wind instrument is an instrument that produces sound by manipulating air through varying the wind pressure passing through the air outputs of the device (Berg and Stock, 27). These devices are heavily dependent on pressure as well as the size and shape of the instrument (pg. 28). A good example of a wind instrument is the organ pipe. It is a tool that produces a specific pitch when pressurized air is driven through it. Organ pipes usually exist in sets, where each is confined to produce a specific tune. Normally, it is a keyboard device that is ...

An EMS controls the vehicle engine in response to both vehicle and engine inputs. It consists of an electronic control unit composed of a micro-processor with several electromechanical and electronic actuators and sensors. Sensor devices are used to monitor the vehicle engine and detect engine speed, lambda values, crank angle and other engine parameters. The electronic control unit determines the engine ignition time, the quantity of fuel and other engine parameters that keep the vehicle engine running. The ECU does this by use of input values that are calculated based on the inputs that originate from the sensors. Under this ...

Introduction

Nebulization is the most effective method for delivering medications to patients suffering from respiratory disease. Nebulizers do not require special inhalation techniques; therefore, hospitals utilize a variety of nebulizer designs for medicinal delivery. One of these devices is called AeroEclipse, which can be operated via one of two different modes. The breath actuation mode generates aerosol only during the patient’s inspiration while the other mode allows for the continuous generation of aerosol particles regardless of the patient’s inspiratory and expiratory efforts. Also, the AeroEclipse has two different patient interfaces: the facemask and the mouthpiece. The hypothesis of this ...

People have been using lift for already more than a hundred years. Lift – is a component of the aerodynamic force which is perpendicular to the vector of the velocity of the motion of an object in the steam of liquid or of a gas which results from asymmetry of the body flow by a stream. It occurs at the motion of any object in the air, if the object has a shape conducive to this (the wing, for example). Air flow around the wing is divided into two streams: over the wing and under it. Lower flow steams in a normal manner having no ...

Introduction

A wind turbine is a device that uses the kinetic energy derived from wind to create mechanical energy. This simply means the wind’s force pushes the blade into motion. Different wind turbines have different ways of extracting wind energy like most machines. Aerodynamics, on the other hand, simply refers to the flow of air about a body. This makes aerodynamics to be a critical aspect of wind turbines as this flow of air about the turbines is what determines its power output. This paper focuses on the aerodynamic behavior of wind turbines (Hansen 21). Calculation of forces acting on a body ...

One of the main problems of classical mechanics is that of turbulent fluid flow. The reason for this is that there is the presence of thin no-slip boundary which requires a lot of meshpoints in order for the solution to be arrived. There is a research which has been arrived and researched upon which shows that with the use of slip boundary condition to be the model for friction to be achieved for the small skin, there is the possibility for predictive simulation for mean quantities. An example of such mean quantities is the drag and lift turbulent flow with millions ...

Introduction

Malta has a publicly funded health care system similar to the one used in the United Kingdom with free health care at the point of delivery for all citizens and registered long term residents. Private health care co-exist along with the public system on a “pay as you use” basis and is mainly used by foreigners and contracted private physicians. The Maltese Ministry of Health is responsible for oversight and regulation purposes besides spear heading campaigns in the health sector. According to Murray & Frenk, Malta has the fifth best health care systems on the world beating developed countries such as the ...

Introduction

A well performing shopping mall should fundamentally have proper Indoor Environment Quality. The importance of a high proper Indoor Environment quality; be it in terms of thermal comfort or air quality cannot be underscored any more. Significant energy goes into creating a high proper Indoor Environment Quality in shopping malls. This energy is used for processes like cooling and ventilation in order to get rid of the high internal gains in heat from electrical appliances, equipment and people. In the recent past, architects have explored the potential for natural ventilation in building spaces (Bauer, MöSle, & Schwarz, 2010, pp.71) Following ...
