Question

The San Francisquito plant no. 1 is supplied by 3 steel-lined penstocks each 80 inches in diameter that carries a combined volumetric flow rate of 712 ft3/s.

Assuming water at 80°F

find

a)Head loss (in feet) due to viscous effect . Include both major and minor losses.

b)Your estimate of the power generation potential in MW.

## Los Angeles Aqueduct Power Development - **1909**: The Bureau of Los Angeles Aqueduct Power was established to create hydroelectric power plants along the Los Angeles Aqueduct. - **March 18, 1917**: San Francisquito Power Plant No. 1, Unit 1 was inaugurated, delivering energy to Los Angeles via a newly constructed 115 kV transmission line. ### Historical Context The left image from circa 1916 shows William Mulholland and Commissioner Del Valle standing inside an 80-inch pipe during the construction of Power Plant 1, highlighting the scale of the infrastructure. ### Facility Overview The right image displays the San Francisquito Power Plant set against a rugged hillside, emphasizing the engineering feat of constructing such facilities in challenging terrains. Note the transmission lines stretching across the landscape, illustrating the distribution network necessary for transporting hydroelectric power to urban areas.

### Image Description for Educational Website This image is a satellite view illustrating the layout of a penstock used in hydroelectric power generation. #### Key Features: 1. **Elevation Points**: - The starting elevation is marked at **3001 ft** and the ending elevation at **2093 ft**. 2. **Penstock Details**: - **Length**: The penstock stretches over a distance of **3,200 ft**. - **Components**: - **Sharp Edged Entrance**: This feature has a loss coefficient (K\_L) of **0.5**. - **45° Elbows**: Includes three elbows, each with a K\_L of **0.4**. - **Sharp Edged Exit**: The exit section has a K\_L of **1.0**. This layout aids in visualizing the terrain and technical elements involved in the energy flow from the water source at higher elevation to the power station. Understanding these elements, including the friction and flow resistance coefficients, is crucial for optimizing the efficiency of hydroelectric systems.
