1) Introduction Momentum is an important concept in mechanics, and its equation is just another different form of Newton’s Second Law which states that “The Rate of change of momentum of a body is equal to the resultant force acting on the body, and takes place in the direction of the force.” A simple definition of momentum is ‘mass in motion’ which means that any object that’s moving has momentum. Also, momentum is the same for any closed system and therefore momentum is conserved, however, momentum of a certain object at some frame is different for the same object at a different frame. So for this lab, momentum is used to help analyze the impact of jet water as it strikes a flat plate. This will be calculated using the theoretical flow momentum of the jet which helps us in finding other properties such as the water speed, jet momentum and force caused due to the impact. The purpose of this lab is to prove that jet momentum and force generated due the impact has a linear relationship between them and that’s because the force generated depends on the same factors that momentum depends on, and therefore they are linear. 2) Procedure First of all, the hydraulic bench supply line was connected to the inlet pipe of the jet impact apparatus while keeping the flat plate at 90 o . The apparatus was leveled by bringing the lever to the balanced position and adjusting
