along a streamline for example down the center Bernoulli equation applies:
p + (1/2) rho v^2 = constant if height does not change
When the diameter decreases, the same amount per second has to flow through a smaller area so velocity increases (continuity)
Therefore
smaller diameter --> faster flow and by Bernoulli thus lower pressure -->2

Option 2

Yes, option 2 is correct. The velocity increases and the pressure decreases when a fluid flows from a larger diameter to a smaller diameter in a horizontal pipe. This is due to the principle of continuity and Bernoulli's equation. According to continuity, the mass flow rate of the fluid remains constant throughout the pipe. As the area of the pipe decreases, the velocity of the fluid increases to maintain this constant mass flow rate. Bernoulli's equation states that in a horizontal pipe, the pressure is inversely proportional to the velocity. Therefore, as the velocity increases, the pressure decreases.
