need to calculate time required to cool-down an element

need to calculate time required to cool-down an element

(OP)
I would like to determine the cooling time of the iron block with dimensions 1000x400 mm. This block is placed in the vessel and cooled by the mass flow of LN2 = 12 g/s. How to specify the time when the iron block reaches a temperature of LN.

RE: need to calculate time required to cool-down an element

It would cool nearly instantly since it is infinitesimally thin.
