Energy conversion

Basal Metabolism Basal metabolism is the minimum amount of energy expenditure required per unit of time that is necessary to conduct involuntary bodily functions such as respiration, blood circulation, muscle tone, maintain body temperature, and ultimately maintain life. The human body requires energy to sustain proper body fluids and nutrients that preserve life and health. An individual’s basal metabolism can be determined by finding their basal metabolic rate. According to Respiratory Care…

it is not fair to compare the two systems based purely on the magnitude of its COP as the work required in a VA refrigerator is produced by heat, it is much cheaper than the work required in VC refrigerator which require electrical or mechanical energy. Environmental issue Conventional VC refrigerant such as CFC or HCFC can deplete the ozone layer and is already phased out based on the Montreal Protocol. Modern VC refrigerant like HFC - also known as f-gases (fluorinated greenhouse gases) - has…

TAQ 1 Explain the term Homeostasis. The term homeostasis is derived from two Greek words; homios meaning ‘the same’ and stasis meaning ‘steady’. It refers to the processes by which the body and internal cells seek to constantly maintain an internal state of balance and equilibrium even when faced with external environmental changes. This is achieved through either positive or negative feedback loop controls associated mainly with the endocrine and nervous systems. Principal homeostatic…

sensing capability of a PZT patch is utilized in sensing conductance to monitor health of a structure. Key features include low cost, small size, dynamic performance, and fast response, long range of linearity, long term stability, and high energy conversion efficiency. PZT patches of any shape, size or thickness can be manufactured at a relatively low cost and it can be used over a wide range of pressures without serious non-linearity. Since it is characterised by a high elastic modulus. If…

gravity, potential energy, kinetic energy, friction, and speed. To our surprise, roller coasters do not typically use engines. If they do, the motor is only used going up the hill and the rest of the ride is motor less. The roller coaster gets energy while it is going up the hills. The roller coaster has the most potential energy when it is located at the first peak which is the highest peak. The fundamental theory of roller coasters has to do with the law of conservation of energy. The initial…

ever. A lot of energy goes into making a car run. First, the electrical energy…

Solar Energy The sun is the most abundant energy source available and used on Earth, hands down. The problem is, much of the energy from the sun that is used on Earth is used by primary producers, not by us, and what they do use is an incredibly small compared to the 89,300 TW retained on Earth at any instant. What we use is smaller still (22). The first step in harnessing the awesome potential our very own star is understanding just how to do that. Think of the inside of a solar cell, the…

years. The dinosaurs drank it and it is being drunk by civilization today. But, technology evolves and the demand for energy is high. There are many ways to produce the energy that people use to fuel their everyday lives whether it is powering a light bulb or to fuel up their eco-friendly electric car the need for energy is endless. For the past years the production of this energy has not have a very positive effect on the environment or on the atmosphere. The burning of coal, natural gas and…

Ground Renewable Expeditionary Energy System (GREENS) is more flexible than SPACES. The main concept of GREENS is to use different sources to generate energy. It reduces the need of fossil fuel and distributes the energy to different sections. Marines use GREENS to generate 300 watts of power. A few GREENS modules can be connected together if more power is needed. There are three configurations for GREENS. Configuration 1 is capable to generate 600 watts for 12 hours, configuration 2 is for 300…
