A perfectly stirred tank is initially filled with 1200 kg solution [T(0)= 70 °Cl Three streams enters this tank: Stream-1(m,=2.6 kg/min, T1=55°C, CP1=2.4 kj/kg.°C). Stream-2 (m2-3.4 kg/min, T2=28 °C, Cp2-4.2 kj/kg.°C). Stream-3 [m3-4 kg/min, T3=75+10exp(-0.05t), T3 in °C, t in minutes, Cp3=3kj/kg.°C]. A single stream (m4-10 kg/min, Cp4=3.2 kj/kg.°C ) leaves the tank. Cp of the solution in the tank at any instant of time is assumed to be also Cp=3.2 kj/kg °C. Which of the following diff. equations describes the variation in the temperature, T (°C) of the solution in the tank with time t (minutes).
