3. Cell culture media flows through a heating tank before entering a bioreactor. The media enters the heating tank at a temperature of 4 C and a mass flow rate of 0.5 kg/min. A stirrer does work at a rate of 50 W, and a heater inputs energy at a rate of 1.3 kW. The specific heat of the media is 4.5 J/(g. C). What is the temperature of the outlet stream at steady-state
