An atmospheric storage tank has a diameter of 20 m and a height of 8m.It is
half-full of liquid with the remainder of the space containing air normally at
atmospheric pressure.
If the connection to atmosphere is accidentally closed off and 10 cubic m of
liquid removed, what happens to the internal pressure of the tank?
What are the possible consequences for the tank?

An atmospheric tank is likely to collapse inward from the
vacuum created by a closed or plugged vent when liquid is
removed from the tank because an atmospheric tank is not
designed to withstand pressures that a pressure vessel can
handle.
