Pressurized pipe flow
A 15-kilometer-long pipe with a pipe diameter of one meter transports water at a speed of one meter per second. The pipe has a friction coefficient of 0.005. Calculate the frictional head loss?
Question
100%
**Problem 10.52** **Context:** Air at a temperature of 40°C flows through a duct at point A with a velocity of 2.0 m/s. The density of air, \( \rho_{\text{air}} = 1.127 \, \text{kg/m}^3 \). **Task (Part A):** Determine the change in pressure between points A and B. Account for the minor loss caused by the sudden change in diameter of the duct. **Instructions:** Express your answer to three significant figures and include the appropriate units. \[ p_B - p_A = \text{Value} \, \text{Units} \] **Submission:** - Enter your answer in the provided text box. - Click "Submit" to record your response. **Provide Feedback:** - A link is provided to offer feedback on the problem setup. **Figure Description:** - The diagram illustrates a duct with a sudden expansion. - The diameter at point A is 200 mm, and at point B, it is 300 mm. - The flow direction is indicated by an arrow pointing from A to B.
