Question: ( 3 0 p t s ) A horizontal pipe has an abrupt expansion from D 1 = 8 c m to D 2 =

(30pts) A horizontal pipe has an abrupt expansion from D1=8cm to D2=16cm. The water velocity in the smaller section is 10ms and the flow is turbulent. The pressure in the smaller section is P1=300kPa. 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.
