a) Determine the amount of heat transferred in a copper plate of area of 3.4 x 10-3 m if T1 is 90 C and T2 is 30 C. Consider a initial distance of 0.3 m and final distance of 5.4 m b) Calculate the cooling temperature of the culture medium after 120 minutes if at 40 min the temperature is 70 C and the values of Ta and To are 28C and To=121C, respectively. c) Determine the maximum biomass that a bacterium can obtain if the oxygen consumption is 500 mmol/(g*h). The bacterium is cultivated in a bioreactor of 10 m and the value of KL= 0.23 s-1. Consider that the oxygen solubility in the culture medium is 3x10-3 Kg/m. a) Determine the amount of heat transferred in a copper plate of area of 3.4 x 10-3 m if T1 is 90 C and T2 is 30 C.
