The document discusses the phenomenon of superconductivity, which is when certain materials exhibit zero electrical resistance and expel magnetic fields when cooled below a critical temperature. It was discovered in mercury in 1911. There are two types of superconductors - type 1 exhibits the Meissner effect and behaves as a perfect diamagnet, while type 2 has a mixed state and does not fully expel magnetic fields. Applications include efficient power transmission, magnetic energy storage, and generators. High temperature superconductors discovered in 1986 could enable more widespread applications.

Hybrid optimization of pumped hydro system and solar- Engr. Abdul-Azeez.pdffxintegritypublishin
Advancements in technology unveil a myriad of electrical and electronic breakthroughs geared towards efficiently harnessing limited resources to meet human energy demands. The optimization of hybrid solar PV panels and pumped hydro energy supply systems plays a pivotal role in utilizing natural resources effectively. This initiative not only benefits humanity but also fosters environmental sustainability. The study investigated the design optimization of these hybrid systems, focusing on understanding solar radiation patterns, identifying geographical influences on solar radiation, formulating a mathematical model for system optimization, and determining the optimal configuration of PV panels and pumped hydro storage. Through a comparative analysis approach and eight weeks of data collection, the study addressed key research questions related to solar radiation patterns and optimal system design. The findings highlighted regions with heightened solar radiation levels, showcasing substantial potential for power generation and emphasizing the system's efficiency. Optimizing system design significantly boosted power generation, promoted renewable energy utilization, and enhanced energy storage capacity. The study underscored the benefits of optimizing hybrid solar PV panels and pumped hydro energy supply systems for sustainable energy usage. Optimizing the design of solar PV panels and pumped hydro energy supply systems as examined across diverse climatic conditions in a developing country, not only enhances power generation but also improves the integration of renewable energy sources and boosts energy storage capacities, particularly beneficial for less economically prosperous regions. Additionally, the study provides valuable insights for advancing energy research in economically viable areas. Recommendations included conducting site-specific assessments, utilizing advanced modeling tools, implementing regular maintenance protocols, and enhancing communication among system components.

Cosmetic shop management system project report.pdfKamal Acharya
Buying new cosmetic products is difficult. It can even be scary for those who have sensitive skin and are prone to skin trouble. The information needed to alleviate this problem is on the back of each product, but it's thought to interpret those ingredient lists unless you have a background in chemistry.
Instead of buying and hoping for the best, we can use data science to help us predict which products may be good fits for us. It includes various function programs to do the above mentioned tasks.
Data file handling has been effectively used in the program.
The automated cosmetic shop management system should deal with the automation of general workflow and administration process of the shop. The main processes of the system focus on customer's request where the system is able to search the most appropriate products and deliver it to the customers. It should help the employees to quickly identify the list of cosmetic product that have reached the minimum quantity and also keep a track of expired date for each cosmetic product. It should help the employees to find the rack number in which the product is placed.It is also Faster and more efficient way.

NUMERICAL SIMULATIONS OF HEAT AND MASS TRANSFER IN CONDENSING HEAT EXCHANGERS...ssuser7dcef0
Power plants release a large amount of water vapor into the
atmosphere through the stack. The flue gas can be a potential
source for obtaining much needed cooling water for a power
plant. If a power plant could recover and reuse a portion of this
moisture, it could reduce its total cooling water intake
requirement. One of the most practical way to recover water
from flue gas is to use a condensing heat exchanger. The power
plant could also recover latent heat due to condensation as well
as sensible heat due to lowering the flue gas exit temperature.
Additionally, harmful acids released from the stack can be
reduced in a condensing heat exchanger by acid condensation. reduced in a condensing heat exchanger by acid condensation.
Condensation of vapors in flue gas is a complicated
phenomenon since heat and mass transfer of water vapor and
various acids simultaneously occur in the presence of noncondensable
gases such as nitrogen and oxygen. Design of a
condenser depends on the knowledge and understanding of the
heat and mass transfer processes. A computer program for
numerical simulations of water (H2O) and sulfuric acid (H2SO4)
condensation in a flue gas condensing heat exchanger was
developed using MATLAB. Governing equations based on
mass and energy balances for the system were derived to
predict variables such as flue gas exit temperature, cooling
water outlet temperature, mole fraction and condensation rates
of water and sulfuric acid vapors. The equations were solved
using an iterative solution technique with calculations of heat
and mass transfer coefficients and physical properties.
1. Introduction
Superconductivity is the phenomenon of exactly
zero electrical resistance.
Expulsion of magnetic fields occurring in certain
material when cooled below a characteristic
critical temperature.
It is a quantum mechanical phenomenon.
It was discovered by
HEIKE KAMMERLINGH ONNES.
(1853-1926)
He discovered that the resistivity
of mercury disappears at
temperature below about 4.2K.
A normal conductor can be brought
into superconducting state by
increasing it’s preasure.
What Is Superconductivity ?
Superconductivity is phenomenon of zero electrical
Resistance & expulsion of magnetic field occurring in
certain materials when cooled below a characteristic
critical temperature (Tc).
The temperature at which electrical resistance
Is zero is called CRITICAL TEMPERATURE (Tc)
Occurrence Of Superconductivity
Superconducting Elements Tc (K)
Sn (Tin) 3.72
Hg (Mercury) 4.15
Pb (Lead) 7.19
NbTi (Niobium Titanium) 10
Nb3Sn (Niobium Tin) 18.1
CeCu2Si2 <1
Ba0.63K0.37BiO3 , SrTiO3-d <30
YBCO, BSCCO, HBCCO <165
General Properties of
Superconductor
Virtually zero electrical resistance.
Perfect diamagnetic property.
Critical Field depends upon temperature of
superconducting material.
Heavy Current effect destroys superconducting
properties.
At very high pressure Tc is directly proportional to
pressure.
Tc is inversely proportional to squre root of At.wt of
the isotope of single superconductor.
High Tc Superconductors
In a superconductor if the transition is high
ie., greater than 20K, then it is called as high
temperature superconductors.
In 1986, Muller and Bednorz discovered high
temperature super conductor
in ceramics.
Structure
“Zero Resistance” - Is It
Possible?
In a normal conductor, an electric current may be
Visualized as a flow of electrons moving across a heavy
Ionic lattice. The electrons are constantly colliding
with the ions in the lattice, and during each collision
some of the energy carried by the electrons is absorbed
by the lattice and converted into heat, which is
Essentially the vibrational kinetic energy of the lattice
ions. As a result, the energy carried by the current
is constantly being dissipated. This is the
Phenomenon of electrical resistance.
In superconductors the situation is completely different
Types of superconductors
Type 1 Type 2
• Exhibit Meissner Effect
• Behave as a perfect
diamagnetic material
• No mixed state in present
• Sudden loss of
magnetization
• Soft superconductor
• There is only one Hc
• Ex., Pb, Sn, Hg
• Does not exhibit
complete
Meissner Effect.
• Does not behave as a
perfect diamagnetic
material.
• Mixed state present
• Gradual loss of
magnetization
• Hard superconductor
• There are two HCs-HC1 &
HC2
• Ex., NbSn, NbTi
Meissner Effect
Magnetic lines of force penetrate through a normal
conducting material when placed in a magnetic field
of flux density B.
Whereas, a superconducting material repels the
magnetic field & thus behaves as a diamagnetic
material.
A superconducting material also ejects magnetic lines
of force when cooled for superconductivity.
