in a factory $1$ cm thick $3*3$ cm square stainless steel plates initially at $170$ C are quenched in a water bath at $40$ C for a period of $2$ min at a rate $150$ plates per minute. if the temperature of the plates after quenching is $60$ C$.$ determine the rate at which heat needs to be removed from the water in order to keep its temperature constant at $40$ C$.$ For the same operating conditions, what materials would you recommend the manufacturerer use to minimize or maximize the heat transferred from the plates to the water? Density $8087$ kg$/$m$3$ and specific heat of stainless steel $0\mathrm{.}50$ kj$/$kgC
