A venturi meter (see figure below) is used to measure water velocity in ahorizontal circular pipe. A mercury manometer is attached to measure the pressuredifferencebetween cross sections 1 and 2 of the venturi meter. Useg= 9.80 m s2 

.a) If the elevation difference of mercury levels at points 1 and 2 is 0.056 m, what is thepressure difference between 1 and 2 (Pa)?

 Determine the flow velocity at cross section 1 (m s1).
