(Solved): A horizontal pipe with a cross-section S1 has a narrowed section with a cross-section S2 ...

A horizontal pipe with a cross-section $$S_1$$ has a narrowed section with a cross-section $$S_2$$ in the middle part. Water flows through the pipe. What applies to the hydrostatic pressure in the water in the narrower and wider part of the pipe: A: The hydrostatic pressure is the same everywhere in the pipe. B: The hydrostatic pressure is higher in the wider part of the pipe where the water velocity is lower. $$\mathrm{C}$$ : The hydrostatic pressure is higher in the narrower part of the pipe where the water velocity is higher.
