Determine the downstream pressure P2, and estimate the error that would have occurred if Bernoulli's equation had been
used, if the horizontal pipe has an abrupt expansion from D1 = 8 cm to D2 = 16 cm. The water velocity in the smaller section
is 10 m/s and the flow is turbulent. The pressure in the smaller section is P1 = 300 kPa. Taking the kinetic energy correction
factor to be 1.06 at both the inlet and the outlet.

The tank and pipe shown in the following figure are initially filled with a liquid ofviscosity μ and density ρ. You can assume laminar flow and ignore exit kinetic-energyeffects. Friction is important in the tube descending from the bottom of the tank, but you canassume negligible friction in the large tank.(a) Apply the energy balance between the free surface of the tank liquid and thedischarge and show that the discharge velocity is the equation seen in the image(b) Use the mass balance to show that the height of the liquid h is governed by the equation in the image(c) Integrate the equation shown in the image and show that the time taken to drain the tankcompletely is:
