Problem 1: Continuity and Energy Balance Below is a schematic of a Venturi device. It is esstentially a pipe with a narrowed section called the Throat, which downstream returns to the orginal pipe diameter. Venturi devices are used to measure flow rates in pipes from the pressure difference between the Main Flow (A) and the Throat (B). For the given Venturi the Main Flow region has a diameter of 5.5 cm and Thorat diameter of 3.3 cm. The the pressure difference between the Main Flow (A) and the Throat (B) has been determined to be 950 Pa. The density of the process fluid is 980 kg/m3. Neglect friction over this small region of the device. Main Flow (A) Throat (B) V1 D1 V2 D2 A. What is the velocity in the Throat (B)? B. What is the velocity of the Main Flow (A)?
