When conducting hydrant testing, where should the Pitot tube be inserted?

The Pitot tube should be inserted into the center of the stream to ensure accurate measurement of the velocity of the water flow. This positioning allows the tube to capture the dynamic pressure of the water as it exits the hydrant, reflecting the true flow conditions. When placed correctly, the Pitot tube effectively measures the kinetic energy of the water, which is crucial for calculating flow rates required for firefighting operations.

By measuring in the center, you minimize the influences of turbulence and other flow irregularities that might occur near the edges of the stream. This center placement is essential for obtaining reliable data that can be used to assess the hydrant's performance and determine if it meets the required standards for firefighting efforts.
