A hydroelectric generation facility has a gross head of 120 m and a consistent yearlong water flow rate of 20 m3/s. The route the facility selected to direct the water to the turbines will require a 1200 m long pipeline. The installed turbines require an intake speed of at least 5 m/s to generate the rated power. If the facility has hired you as a consultant to design the pipeline and they told you that they will only tolerate a head loss of only 10 meters. What will be the diameter and the material (best option) of the pipeline that you will recommend the facility to install? Consider an average water temperature of 10 °C throughout the pipeline.

Question

A hydroelectric generation facility has a gross head of 120 m and a consistent yearlong water flow rate of 20 m3/s. The route the facility selected to direct the water to the turbines will require a 1200 m long pipeline. The installed turbines require an intake speed of at least 5 m/s to generate the rated power. If the facility has hired you as a consultant to design the pipeline and they told you that they will only tolerate a head loss of only 10 meters. What will be the diameter and the material (best option) of the pipeline that you will recommend the facility to install? Consider an average water temperature of 10 °C throughout the pipeline.

1.
2.
Use the link and choose three states (https://www.hydro.org/map/hydro/existing-hydropower_) and find out
what type of hydropower systems they have and what is the hydropower production as percentages and
compare the states. Write one or two paragraphs regarding your comparison; what you expect and what you
found.
Estimate the required flow for a 10,000 MW e hydro installation as a function of the effective hydraulic head
from 10 to 300 m.
3. A community requires 40 kW of power output to meet their daily electricity needs. If the site survey indicates
90 m of gross head to be available, what design discharge is required to meet the community's electricity
needs? Assume an overall efficiency of 65%.
4. Assume that the US wants to expand its hydropower capacity to its full technical potential without building
any new dams as a means of offsetting carbon dioxide emissions from coal-fired plants. Estimate the impact
on annual carbon dioxide emissions. What would be your estimate of capital investment needed to
accomplish this?

5. A hydroelectric generation facility has a gross head of 120 m and a consistent yearlong water flow rate of 20
m³/s. The route the facility selected to direct the water to the turbines will require a 1200 m long pipeline.
The installed turbines require an intake speed of at least 5 m/s to generate the rated power. If the facility has
hired you as a consultant to design the pipeline and they told you that they will only tolerate a head loss of
only 10 meters. What will be the diameter and the material (best option) of the pipeline that you will
recommend the facility to install? Consider an average water temperature of 10 °C throughout the pipeline.
Use the link https://waterwatch.usgs.gov/?id=ww current to download the streamflow data. Choose one river;
1. Create a plot for the mean monthly flow.
2. Create the flow duration curve.
3.
What kind of turbine do you choose based on flow rate? Explain briefly.
