b) An industrial process involves the measurement of the flow rate of water in a pipeline using an orifice plate of area Ao, which is related by the following equation. Ca Ao |2ΔΡ X 2 i) Sketch its construction ii) Calculate the pressure difference (AP) across the flow sensor, given the following parameters: - Volumetric flow rate, Q = 0.025 m³/s Discharge coefficient, C₂ = 0.6 Density of water, p = 1000 kg/m³ Internal diameter of pipe, Dp = 100 mm Diameter of orifice, D, = 50 mm The orifice plate is replaced by a Venturi tube with identical parameters, but with a discharge coefficient of 0.96. Comment upon its AP relative to that of the orifice plate. (2 Based on your results from Parts b) and c), which type of flow meter would you recommend and why? Name an alternative flow measurement device and briefly describe its operation. c) d) e) (2 (2
