The Rhett Peach, Co. dips the peaches in boiling water (120C) to remove the skin (a process called blanching) before canning them. The wastewater from this process is high in organic matter and it must be treated before disposal. The treatment process is a biological process that operates at 30C. Thus, the wastewater must be cooled to 30C before disposal. Forty cubic meter of wastewater is discharged toa concrete tank at a temperature of 30C to allow it to cool. Assuming no losses to the surroundings, that the concrete tank has a mass of 35,000 kg and a specific heat capacity of 0.93 kJ. Kg-1. K-1, what is the equilibrium temperature of the concrete tank and wastewater
