$1\mathrm{.}8$ Tons of Organic Liquid $($Sp$.$gr $1\mathrm{.}5,$ Thermal Conductivity $0\mathrm{.}17$ W$/$mK$)$ is at $280$DegC in a well agitated closed ss$316$L Vessel $($Shell Thickness $5$mm$,$ Internal surface area $8$ m$2,$ Internal volume $18\mathrm{.}65$ m$3,$ thermal conductivity $15$ W$/$mK$).$ Time taken to cool the liquid to $100$DegC naturally. Cooling Tower capacity in TR required to cool it in $30$ minutes $($from $280-100$DegC$)$ and quantity of circulating water and pump capacity required.
