2: (25 points) A) Consider the Venturi meter shown in the figure below. Between the entrance and exit, water flows from the pipe of cross sectional area A_(i), diameter d_(1)=0.3m with speed v_(1) and then through a narrow "throat" of cross sectional area A_(2), diameter d_(2)=0.15m with speed v_(2). The static pressures pi and p_(2) are measured by two measuring tubes filled with water. The change in the fluid's speed is accompanied by a change in the fluid's pressure, which causes a height difference h=0.2m. Assume an ideal fluid flow. (5 points) a) Determine the flow speeds: v_(1) and v_(2). b) Calculate the volume flow rate
