Prоblem 2 (30 pts) Wаter flоws thrоugh а horizontаl pipe at a rate of 0.0025 m3/s. The pipe consists of two sections of diameters D = 0.18 m and d = 0.06 m with a smooth contracting section. The pressures at the two pipe sections (designated as 1 and 2 in the figure) are measured by pressure gauges. The reading at section 1 gives P1 = 1,000 Pascals. Neglecting frictional effects, determine the following (use density of water = 1,000 kg/m3): The average velocities at sections 1 and 2, which are v1 and v2, respectively, in m/s. The value of P2, in Pascals If a mercury manometer is used to measure the difference in pressure between sections 1 and 2, in which section would the mercury level be higher?
