8-61 A horizontal pipe has an abrupt expansion from Dj = 5 cm to D2 = 10 cm. The water velocity in the smaller Page 429 section is 8 m/s and the flow is turbulent. The pressure in the smaller section is P1 = 410 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 Bernoulli's equation had been used. Answers: 423 kPa, 17.3 kPa D2 = 10 cm D = 5 cm Water 8 m/s 410 kPa FIGURE P8-61
