COST ESTIMATION OF SMALL HYDRO POWER GENERATIONRajeev Kumar
R. Montanari [4] in his paper presents an original method for finding the most economically advantageous choice for the installation of micro hydroelectric plants. More precisely, the paper that follows is to be considered in a context defined as “problematic” by those who have the job of constructing water-flow plants with only small head and modest flow rates. Traditional plant solutions using Kaplan or Francis type turbines must be rejected because of the high levels of initial investments. Much more simple configurations must be analyzed, such as plants with propeller turbines or Michel–Banki turbines, in order to reduce the investment costs. The general methodology applied provides a powerful decision-making instrument which is able to define the best plant configuration. The method is based on the use of economic profitability indicators, such as the Net Present Value (NPV), calculated using the plant project parameters, the nominal flow rate and head, and the particular hydrologic characteristics of the site, such as the type of distribution, the average value and the standard deviation of the flow rates in the course of water supplying the plant
S.M.H. Hosseinia, F. Forouzbakhshb, M. Rahimpoor [6] in their paper a method to calculate the annual energy has presented, as is the program developed using Excel software. This program analyzes and estimates the most important economic indices of a small hydro power plant using the sensitivity analysis method. Another program, developed by Mat lab software, calculates the reliability indices for a number of units of a small hydro power plant with a specified load duration curve using the Monte Carlo method. Ultimately, comparing the technical, economic and reliability indices will determine the optimal installation capacity of a small hydro power plant.
S.K. Singal and R.P.Saini [9] has presented methodology to determine the correlations for the cost of different components of canal based small hydro power schemes. The cost based on the developed correlations, having different head and capacity, has been compared with the available cost data of the existing hydropower stations. It has been found that these correlations can be used reasonably for the estimation of cost of new canal-based SHP schemes.
The presentation covers: History of Development in India, Current Status & Potential of Hydro Power, Necessity of HP Development, Advantages and Disadvantages of Hydropower, Comparison between Hydro Power, Thermal Power and Nuclear Power, Challenges/Barriers in Development of HP, Place of Hydro-Power in Power System

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.
CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!
Work done in cooperation with James Malloy and David Moelling from Tetra Engineering.

RAT: Retrieval Augmented Thoughts Elicit Context-Aware Reasoning in Long-Hori...
Hydropower Potential, History, Challanges, Possibilities and New Trend of Development in Nepal
1. HYDROPOWER POTENTIAL IN NEPAL, HISTORY,
CHALLENGES, POSSIBILITY AND NEW TREND IN
HYDROPOWER DEVELOPMENT
2. OUTLINE OF THE PRESENTATION
- Hydropower potential in Nepal
- Its history
- Its challenges
- Its possibilities
- New trend of hydropower development
3. HYDROPOWER POTENTIAL OF NEPAL
- Second richest country in water resources
- 83000 MW ( based on 1966 PhD. of Dr. Hari Man Shrestha)
- More scientific study shows 53000 MW ( Professor Narendra Man
Shakya)
- Economically and technically feasible is 43000 MW ( National Planning
Commission 1985)
4. HISTORY OF HYDROPOWER DEVELOPMENT
- Pharping Hydrpower Plant is oldest hydropower plant of Asia and first
hydropower plant of Nepal
( Established in 1911 )
- Ironically we have lagged behind in hydropower generation ever since
- Faced the problem of loadshedding for long duration
- Consumption has always been higher than production rate
5. CHALLANGES FOR HYDROPOWER DEVELOPMENT
- Political constraints
- Technical constraints
- Financial constraints
- Policy constraints
- Climate change
6. POLITICAL CONSTRAINTS
- Lack of political will and political instability
- Natural resources and revenue sharing with India
- State reconstruction made the progress works more slower recently
7. TECHNICAL CONSTRAINTS
- Related to geographical, hydrological and topographical setting of country
- Lack of long term hydrological and sediment logical data
- Lack of specialized manpower
- Insufficient capacity of existing and planned cross border transmission lines
8. FINANCIAL CONSTRAINTS
- Big hydropower projects need huge investments
- The domestic investment is not sufficient and Foreign Direct Investment
(FDI) is lagging owing to several reasons
- Pricing issue of electricity
9. POLICY CONSTRAINTS
- Issue of license and institutional constraints
- Monopoly of NEA over transmission and distribution sector
- Overlapping responsibilities among government ministries and departments
- Inconsistency among various hydropower development policies
10. CLIMATE CHANGE
- Run off variability
- Glacial lake outburst flood
- Sediment and evaporation loss
11. POSSIBILITIES OF HYDROPOWER PRODUCTION
- Blessed with water resources
- Can totally meet its energy demand through hydroelectricity production if
resources are properly used
- Recent local participation in investment for hydropower generation is a good
sign for its development
- When the whole world is running towards clean energy generation, hydro
resources can be best for Nepal
12. NEW TREND OF HYDROPOWER DEVELOPMENT
- Some big hydropower projects are under construction
- Some are nearer to completion phase
- Recently in 2017, 115 MW of hydropower production was increased in our
country
(International Hydropower Association | 2017 Hydropower Status Report)
The Draft Electricity Act- 2065 has stipulations that no license is required for up
to 3 MW capacity.
This creates a positive environment for the development of small hydro.
13.
14. Development in micro hydropower generation in villages have :
- Changed the night landscape
- Streets are illuminated
- Silence in evenings is filled with news broadcast
- Reading in evening has become easier to students
- Small scale industries are established helping eradicate the unemployment
problem
15. Despite long history of hydropower development, there still persists various
hurdles and drawback in hydropower sector.
It seems that Nepal’s hydro-bureaucracy is slow to understand the right thing to
do.
16. It took about 20 years for the hydro-bureaucracy of the Nepal Government
to understand that private sector is not capable to develop sufficient hydropower
projects to satisfy the demand; and the public sector must play a substantial and
major role for implementation of hydropower projects.
Similarly, after more than 20 years Nepal’s hydro-bureaucracy has yet to
understand the reality that Indian Power market is not open to Nepal, especially
if it is developed by other than the Indian companies.
17. It has been announced a People’s Hydropower for constructing upto 25 MW
hydro project by District Development Committee (DDC) and local institutions.
Hydropower development in Nepal is a difficult Task. For example, Khudi HEP
4MW developed by the top Hydro Developer of Nepal is loss making project.
Similarly, 5 MW Mailung Khola HEP is promoted by the hydro power
Engineers/professionals who have spent their life time in hydro projects also
suffered loss.
18. With all ups and downs the hydropower generation in Nepal is in
developing phase.
No doubt that Nepal is rich in water resources and we must grab it all
for our long term prosperity and BRIGHTER NEPAL.
19. THANK YOU ALL !!!

Editor's Notes
First hydropower plant in china was build in 1912
Dependent on india for power import
Agreements for water resources uses
For irrigation in india
Limited hydropower production in Nepal
High, slopy and steep hills and mountains
Difficult landstructure
Difficult for station establishment and transmission of energy as load centre is in urban or plain area
Produce garesi trsnsmit garna lai belaima no line
Reasons like
Lack of security for investment
Frequent policital situation fluctuation
Most hydropower run off , so run off variability majorly affects the production
Flood causes sweeping of power house damaging civil and electro mechanical structures
Sediments increases tearing and wearing of machines In power house
Integrated Nepal Power System or national grid mostly covers the areas of terai and some part of hilly area
Most part pf hilly and mountain areas have no access to national grid
So isolated hydropower plant can be the best solution
And recently investment in isolated micro hydropower plant is increasings
Local people investment, government investment
Labour support
Other organization United Nations Development Programme (UNDP)
Lets take some examples
It is still dreaming of exporting substantial power to earn hydro- rupees/dollars. Sixteen years of efforts failed to develop West Seti HEP (750 MW).
It is a clear signal that Indian power market is not open to Nepal.
It is a
good initiative to have people’s hydropower. 25 MW is too big
for a DDC in terms of its managerial, technical, and financial
capability. State owned agency NEA and reputed private
developers are getting tough times to develop even a
small project.
Hydropower plants with large capacity must be given higher priority in development as at recent the energy production and consumption are new parameters for development of any country.
