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?
Answer / carl_ellis
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.

Hi friends, from Aug 4th onwards iam getting spikes for analog inputs in our DCS for a period of 800ms. I throughly checked every thing, finally i found that the DI, DO's from MCC panels shields are terminated in the Signal Earth where Analog Input signals shields are terminated. Is there any problem with this type of termination?. i checked the induction voltage from MCC and getting around 25VAC, please suggest me in this concern. Our plant is 8months old only. DCS is Siemens Make Simatic PCS7, and the transmitters are Yokogawa make.
