Ahorizontal pipe has an abrupt expansion from d1 = 5 cm to d2 = 10 cm. the water velocity in the smaller section is 8 m/s and the flow is turbulent. the pressure in the smaller section is p1 = 370 kpa. taking the kinetic energy correction factor to be 1.06 at both the inlet and the outlet, determine the downstream pressure p2, and estimate the error that would have occurred if bernoulliās equation had been used. take the density of water to be Ļ = 1000 kg/m3.
