Question
Suppose the tank is operating in the steady state of part (a) with all flow rates and amounts as indicated in the problem statement, T1
Suppose the tank is operating in the steady state of part (a) with all flow rates and amounts as indicated in the problem statement, T1 = 20C, and T = T2 = 30C. Now the heater is shut off. Assuming the tank is perfectly insulated from the surroundings, write and solve the differential equation for the tank tem- perature T(t). How many minutes will it take for the water in the tank to fall to 25C?
