Force On Plate: Distance, M

This document contains data from an experiment measuring fluid pressure and flow rate. Tables of measurements show fluid levels in a manometer and pressure readings for different angles of a Pitot tube positioned vertically in a fluid flow. Graphs plot the relationship between flow rate and back pressure, as well as fluid levels and angle of the Pitot tube. The document also includes equations relating pressure, density, and flow velocity.
