2. A venturimeter is used to determine the flow of water through the reading of a manometer connected through it (Figure 1). Figure 1: Schematic diagram of a venturimeter. 15p7 The relationship between the pressure drop and flow rate is as follows: P – P, = - 24 Where, V = Volumetric flow rate of water. P1, P2= Pressure at point 1 and point 2 respectively. p= Density of the fluid, and Ai= Area at point 1. Data: Density of water = 1000 kg/m³. Diameter if inlet pipe = 2 m.
