Question
Air at a temperature of 40∘C∘C flows through the duct at A� with a velocity of 1.9 m/sm/s . ρair�air = 1.127 kg/m3kg/m3
Determine the change in pressure between A� and B�. Account for the minor loss caused by the sudden change in diameter of the duct.
Express your answer to three significant figures and include the appropriate units.
![**Problem Statement:**
Air at a temperature of 40°C flows through the duct at point \( A \) with a velocity of 1.9 m/s. The density of air (\( \rho_{\text{air}} \)) is given as 1.127 kg/m³.
**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.
Express your answer to three significant figures and include the appropriate units.
\[ p_B - p_A = \_\_\_\_ \]
Please write your value and units in the provided space. If needed, use the unit conversion buttons for assistance.
**Figure Description:**
The figure illustrates a duct with a sudden change in diameter. The duct narrows from a diameter of 300 mm at section \( B \) to 200 mm at section \( A \). Air flows from left to right through the duct, entering at section \( A \) (200 mm diameter) and exiting at section \( B \) (300 mm diameter).
**Instructions:**
- Use the principles of fluid dynamics to calculate the pressure difference.
- Consider the effects of the sudden expansion.
- Submit your answer for assessment.
