An engineer needs to control the flow of gasoline (density = 680 kg/m3, viscosity= 2.92x10-4 kg/ms) at 20C with a flow rate of approximately 1 + - 0.1 m3/min through a 10 cm diameter smooth pipe. For this, he is considering using either an orifice plate or a venturimeter with a 5 cm diameter bottleneck. Since the only available pressure gauge that the engineer can use can measure accurately in the range of 40-70 kPa, find out which device the
