A water pipe is inclined 31.0° below the horizontal. The radius of the pipe at the upper end is 2.00 cm. If the gauge pressure at a point at the upper end is 0.122 atm, what is the gauge pressure at a point 2.70 m downstream, where the pipe has narrowed to a 1.00 cm radius? The flow rate is 20.0π cm3/s.

All of these are covered by Bernoulli's law, do you have any specific questions on the use of that? https://www.khanacademy.org/science/physics/fluids/fluid-dynamics/v/fluids-part-8 and the followon three parts are very good
im still very confused
