Electrical DC Waveform Frequency

One wave per second is also called a Hertz Hz and in SI units is a reciprocal second s 1 . The variable c is the speed of light. For the relationship to hold mathematically, if the speed of light is used in m s, the wavelength must be in meters and the frequency in Hertz. So what would be frequency of DC waveform weather it’s 0 HZ or more than 0 HZ up to 1 HZ

Harvesting Renewable Energy by Using Human Foot Step

Man has used tremendous amount of energy for his daily needs. Due to this a lot of energy resources have been exhausted and wasted. Proposal for the utilization of waste energy of foot power with human locomotion is very much relevant and important for highly populated countries like India where the railway station, temples etc., are overcrowded all round the clock. In this paper the force energy is produced by human footsteps and the force energy is converted into mechanical energy by rack and pinion mechanism, electricity is produced by dc generator. And this power source has many applications as in agriculture, home application and street lighting and as energy source for sensors in remote locations. This thesis is all about generating electricity when people walk on the Floor. Think about the forces you exert which is wasted when a person walks by. The idea is to convert the weight energy to electrical energy The Power generating floor intends to translate the kinetic energy to the electrical power. Energy Crisis is the main issue of world these days. The motto of this research work is to face this crisis somehow. Though it won’t meet the requirement of electricity but as a matter of fact if we are able to design a power generating floor that can produce 100W on just 12 steps, then for 120 steps we can produce 1000 Watt and if we install such type of 100 floors with this system then it can produce 1MegaWatt. Which itself is an achievement to make it significant.

CFD Analysis of a W Ribbed Roughness Solar Air Heater

Solar air heaters are used to heat up air which can be used for various purposes. Computational Fluid Dynamics CFD has proved to be a boon for researchers to estimate performance of any machine at design stage only. In the present work, a 3 dimensional CFD investigation has been completed of sun powered air radiator to ponder heat exchange and liquid stream conduct in a rectangular pipe of a sun oriented air warmer with one roughened divider having blend of round and square transverse wire rib harshness. The impact of Reynolds number, harshness tallness, unpleasantness pitch, relative unpleasantness pitch and relative harshness stature on the warmth exchange coefficient and rubbing factor have been considered. From the investigation it has been found that, W formed harshness gives better warmth exchange rate as contrast with the V rib unpleasantness under comparable working conditions. The most extreme estimation of Nusselt number for W formed harshness is acquired with the relative unpleasantness pitch P e of 10 past that it begins diminishing.

Development and Performance of Electro Hydraulic Excavator

The heavy earth moving machineries HEMM like hydraulic excavators play a major role in the construction and mining industries. In an industry of mining and construction, a hydraulic excavator plays a major role in action to perform a carry an heavy load. Employing the technology of automation, an alternative solution is made to replace the manual operation. By addressing the concept of automation in construction, the inevitable usage of embedded is accumulated to introduce in earthmovers. In a mass production or construction site, unplanned work would lead to time consuming and fault. To overcome the major disadvantage of time consuming, so implementation of automation is made on excavators. This could be made workers do other work sequentially with half monitoring the working process of excavator. This also favors the firm or industry to increase the work capability with an adequate number of laborers.

Design of Rocking Chair for Energy Generation Purpose

This paper mainly focuses on the design of rocking chair for energy generation purpose. Energy plays key role in daily life to satisfy the needs. Technology development is gradually increasing day by day. The traditional method of energy consumption is getting down due to high energy demand. In order to satisfy the need of energy, the new method of energy consumption technique is discussed in this chapter.

Flexural Behaviour of Steel Fiber Reinforced GEO Polymer Concrete

Concrete is the most used development fabric from historic days. It used to be anticipated that the manufacturing of cement would be accelerated from about from 1.5 billion lots in 1995 to 2.2 billion lots in 2020. But 2018 china the usage of 2.37 billion lots individually. India is the 2nd biggest producer of cement in the world. Cement enterprise is anticipated to attain 550  –  600 million lots per annum at 2025. The cement manufacturing contributes almost 8 of worlds world warming due to emission of greenhouse gases, such as CO2, to the atmosphere. Hence, it is indispensable to discover a replacement cloth for cement. The technological know how Geo polymer concrete determined as choice for this problem. In this existing research, cement is changed with Fly Ash and GGBS in distinct percentages with steel fibers. The research exhibit that the load carrying capability of most of the gpc combine was once in the most instances extra than that of traditional normal Portland cement concrete mix. The clean and hardened homes of geo polymer concrete had been observed with and except metal fiber. The mechanical traits of all the examined mixes are to be more suitable with the aid of the GGBS content, in each undeniable and metal fiber strengthened geo polymer concrete. A comparative evaluation has been carried out for regular traditional concrete to that of the metal fiber strengthened geo polymer concrete below ambient curing in relation to compressive, break up tensile, flexural strengths. As the fiber content material normally will increase compressive, cut up tensile and flexural strengths are proportionally increased.

Experimental Study of Mechanical Properties of Sintered Fly Ash Aggregate in Concrete

This paper gives the work carried out for the enhancement of mechanical residences of sintered homes fly ash mixture in concrete. Fiber Reinforced Concrete is a composite fabric consisting of a matrix containing a random distribution or dispersion of small fibers, having a excessive tensile strength. Alkali resistant glass fiber prevents corrosion and helps enhance concrete properties. Like make bigger tensile strength, enhance resistance to impact, amplify shear strength, higher water resisting properties. Glass fibers weight is lots lighter than when metal is used in concrete. Good freeze thaw resistance helps shield various climatic stipulations at marine environments in very bloodless international locations In this study, Conventional concrete has the trait regarded as brittle failure due to the fact it has a semi crystalline structure, which tends to shatter on impact. This is mainly risky when subjected to explosive pressure due to the fact ballistic particles is created which can create giant collateral damage. This is no longer the case with GRFC, as it does no longer ride brittle failure. it is determined to scan locate out the power and sturdiness of the Glass Fiber Reinforced Concrete made the usage of Cement for assessing its suitability for Marine and Hydraulic Constructions.
