An electric heater is immersed in a well-stirred tank. Solvent at 19°C, which has a heat capacity of 2.1 kJ/(kg°C), is fed at a speed of 11 kg/h. The hot solvent is discharged at the same rate. The tank initially contains 180 kg of cold solvent at 10°C. The heat flow of the electric heater is 884 W. Calculate the time for the temperature of the solvent being discharged to be 63°C (write the answer in hours and with two...

Please answer with words as well Question 3. A well-stirred cylindrical tank contains a volume V of liquid. The flow rate of the liquid into and out of the tank is Q. The concentration of a dilute, inert tracer in the feed stream is C, which is a function of time, t. A differential equation describing the variation of the concentration of the tracer in the tank, C, can be derived as: V dC dt - The concentration of the...
