Ql- Water flows at a rate of 0.040 m/s in a 0.12-m-diameter pipe that contains a
sudden contraction to a 0.06-m-diameter pipe. Determine the pressure drop across
the contraction section.
How much of this pressure difference is due to losses and how much is due to
kinetic energy changes?
Q2- Air at 59°F and standard atmospheric pressure flows through a furnace filter
with an average velocity of 2.4 ft/s. If the pressure drop across the filter is 0.06 in.
of water, what is the loss coefficient for the filter? Specific Weight (y) of water =
62.4 Ib/ft³.

Q3- Water flows downward through a vertical 10-mm-diameter galvanized iron
pipe with a Reynold No. 100000 and exits as a free jet. There is a small hole in the
pipe 4 m above the outlet. Determine the velocity that we release to make the
pressure at the hole is zero?
