design of 30tonne split water tank
hi there,
i need to design a 3m high 3600mm diameter split water tank with a capacity of up to 30 tonnes of high temp water open to the atmosphere. there is not enough room for two tanks and this tank will be built over the top of the old one.
one side will be full most of the time and the other side will only be used when the water from one side is diverted when found to be contaminated. i am thinking as one side is going to normally be empty that i will have hoop stress problems and the like. i am looking for any information on open atmosphere split circular tanks. does anyone know where i could find this?
thanks in advance,
dc

concentric cylinders are definitely more feasible, because you still have membrane rather than bending stresses. any flat plate caries a load via bending stresses, which is much less efficient than membrane action. a circular tank with a straight dividing baffle would need very thick plate for both the baffle and the shell.
yet you are thinking steel plate or so, i muse. in zaragoza (spain) where i live we make reinforced concrete tanks with walls even 40 cm thick for alike volumes (and divided) to hold water for fire prevention control without blinking an eye, so economy of 1 off items is many times in the eye of the beholder.
