Question
![**Energy Equation:**
**Example 2:**
A horizontal pipe carries cooling water at 10°C for a thermal power plant. The head loss in the pipe is
\[ h_L = \frac{0.02 \left(\frac{L}{D}\right) V^2}{2g} \]
where \( L \) is the length of the pipe from the reservoir to the point in question, \( V \) is the mean velocity in the pipe, and \( D \) is the diameter of the pipe.
If the pipe diameter is 20 cm and the rate of flow is 0.06 m\(^3\)/s, what is the pressure in the pipe at \( L = 2000 \) m? Assume \(\alpha_2 = 1\).
**Diagram Explanation:**
- The diagram shows a pipe system where a horizontal pipe carries water.
- The pipe starts at a reservoir positioned at a height of 80 m (Datum level).
- The diameter of the pipe is labeled as \( D = 0.2 \) m.
- The length of the pipe from the reservoir to the endpoint is marked as \( L = 2000 \) m.
- The flow rate in the pipe is indicated as \( Q = 0.06 \) m\(^3\)/s.
- The head loss equation is provided with the diagram to illustrate the calculation of energy losses in the system.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F89ff9c08-d82f-4c45-91c3-3510df7b72b7%2Fedde809c-1c1c-4692-921c-351c0157074b%2Fihagz6_processed.png&w=3840&q=75)
