A horizontal pipe has an abrupt expansion from D1 = 8 cm to D2 = 16 cm. The water velocity in the smaller pipe is 15 m/s and the flow is turbulent. The pressure in the smaller pipe section is P1 = 350 kPa. Taking the kinetic energy correction factor to be 1.08 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.
