Kulekhani Reservoir

Kulekhani Reservoir is a engineering topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Kulekhani Reservoir rather than just read about it. In short: The Kulekhani Dam is a rock-fill dam on the Kulekhani River near Kulekhani in the Indrasarowar Rural Municipality of Makwanpur District in Bagmati Province, Nepal. The primary purpose of the dam is hydroelectric power generation and it supports the 60 MW Kulekhani I, 32 MW Kulekhani II and 14 MW Kulekhani III Hydropower Stations.

Key takeaways

Kulekhani Reservoir belongs to engineering; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Kulekhani Reservoir to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Kulekhani Reservoir from memory before moving on to harder problems.

Reference excerpt

The Kulekhani Dam is a rock-fill dam on the Kulekhani River near Kulekhani in the Indrasarowar Rural Municipality of Makwanpur District in Bagmati Province, Nepal. The primary purpose of the dam is hydroelectric power generation and it supports the 60 MW Kulekhani I, 32 MW Kulekhani II and 14 MW Kulekhani III Hydropower Stations. Construction began in 1977 and Kulekhani I was commissioned in 1982. Kulekhani II was commissioned in 1986 and a third power station, the 14 MW Kulekhani III was expected to be commissioned in May 2015 but was delayed due to issues with the builder. The US$117.84 million project received funding from the World Bank, Kuwait Fund, UNDP, Overseas Economic Cooperation Fund and OPEC Fund. It is owned by Nepal Electricity Authority. The 114 m (374 ft) tall dam creates a reservoir called Indra Sarobar which stores 85,300,000 m3 (69,200 acre⋅ft) of water. The Kulekhani Dam in Nepal has a total installed capacity of 106 megawatts (MW):

Kulekhani I: 60 MW installed capacity Kulekhani II: 32 MW installed capacity Kulekhani III: 14 MW installed capacity

Kulekhani I hydropower station From the reservoir, water is sent to the Kulekhani I Hydropower Station via a 5.8 km (3.6 mi) headrace tunnel to a gate house which controls the flow of water to the power station. From the gate house water travels down a 1,340 m (4,400 ft) long penstock where it reaches the underground power station. It contains two 30 MW Pelton turbine-generators. The difference in elevation between the reservoir and the power station affords a net hydraulic head of 550 m (1,800 ft).

Kulekhani II hydropower station Water discharged from the Kulekhani I power station enters a series of tunnels and diversions where it reaches the Kulekhani II Hydropower Station which is also located underground and contains two 16 MW Francis turbine-generators. The elevation difference between the reservoir and the power station affords a net hydraulic head of 284.1 m (932 ft). The dam and reservoir are in the Bagmati River basin while the power stations are in the Rapti River basin.

Kulekhani III hydropower station Construction of the Kulekhani III Hydropower Station had been underway since 2008 and was completed in 2019. The Nepal Electricity Authority (NEA) had extended the completion deadline of the Kulekhani 3 Hydropower Project for the fifth time to January 2018 as construction was running late due to its slowpoke contractor. The project’s civil contractor Sino Hydro has completed 100 percent of the construction, and there has been full progress in the installation of the turbine, water gate and transmission lines to evacuate the electricity generated by the plant. It will use the tailwaters of Kulekhani II and have an installed capacity of 14 MW.

Worked examples

Example 1 — a first encounter with Kulekhani Reservoir

Start with the simplest possible case. Write down what Kulekhani Reservoir claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In engineering, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Kulekhani Reservoir before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Kulekhani Reservoir ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Kulekhani Reservoir

In research: Kulekhani Reservoir appears in engineering research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Kulekhani Reservoir in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Kulekhani Reservoir is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1982 establishments in Nepal, Artificial lakes of Nepal, Buildings and structures in Makwanpur District, so understanding it makes those chapters shorter.
In everyday life: Look for Kulekhani Reservoir outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
