This document contains instructions for Assignment 4 in the MET212 Fluid Mechanics & Machines course. It includes 3 problems to solve: 1) Calculate the discharge rate through a Venturi meter given the pressure difference of 150 kPa and other provided data. 2) Calculate the force and work done per second on a flat plate impacted by a jet of water moving at 0.5 m/s at an angle of 60 degrees, given the jet radius and discharge rate. 3) Calculate the discharge of flow through a pipe connected to an open water tank, and determine the height needed to create a vacuum pressure of 30 kPa below atmospheric, given elevation changes, pipe lengths, and friction factor.
