Fluid mechanics - Problems on Orificemeter and Inclined Venturimeter

This document provides an overview of orificemeters and their use in measuring fluid flow. It discusses how orificemeters work by using an orifice plate with a circular hole to cause a pressure drop according to Bernoulli's equation. The rate of discharge is calculated using the orifice diameter and upstream and downstream pressures. Examples are given of orificemeter setups in laboratories and their advantages over venturimeters in being cheaper while still providing accurate flow measurements.
