There is a conveyor that will be used to pass the $500-$gram liquid plastic packaging product which is put into a stainless$-$steel mold $($the final product shape is square$).$ The initial temperature of the product that is put into the stainless$-$steel mold is $80oC,$ after passing it to the conveyor which has a cooling blower at the top of the conveyor, the final product temperature is expected to be $40oC.$ The length of the conveyor is $5$ meters.

a$.$ How much energy is needed to cool the temperature of the product?

b$.$ How much cooling blower flow is needed for the cooling process?

c$.$ Determine the required cooling blower specs and quantity?
