Water flows from a very large tank through a 5cmdiameter tube. The dark liquid in the
manometer is mercury. Estimate the velocity in the pipe and the rate of discharge from the tank.
(Assume the flow is frictionless.)

Water flows steadily through the reducing elbow shown. The elbow is smooth and short, and
the flow accelerates, so the effect of friction is small. The volume flow rate is
𝑄

. The
elbow is in a horizontal plane. Estimate the gage pressure at section
①
. Calculate the

component of the force exerted by the reducing elbow on the supply pipe.
