![**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.
\[ p_B - p_A = \text{Value} \, \text{Units} \]
