A venturi tube like the one shown in the figure is used to measure the volumetric flow rate of kerosene (SG=0.85). Figure 2. Ref Figure for Q2 a. Suppose the venturi is used to measure volumetric flow rates up to 0.05sm3. what is the maximum pressure drop that the system should register? (marks 15) b. Suppose the fluid is changed to water ( SG=1.0). What is the maximum volumetric flow rate for water if the manometer can register a maximum pressure difference of approximately 116kPa ? (marks 10) c. Provide a physical explanation of why the volumetric flow rate changes with the fluid change. (marks 5)
