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.

1. I have taken a sound reading and my sound level meter (SLM) is showing the result in Pascals, not dB (shouldn't have bought a cheap one). The maximum pressure shown is 101,008 Pa. Before the noise started, the air pressure was about 101,001 Pa, so the noise increased it by just 7 Pa. This doesn't seem right because the noise was really loud. Is my meter broken? What is the noise level in decibels (WRT 20µPa)?
