A 15% Na2SO4 solution is fed at a rate of 5.5 kg/min into a mixer which initially holds 45.5 kg of a 50-50 mixture of Na2SO4 and water. The exit solution leaves the mixer at a rate of 4.5 kg /min. Assuming uniform mixing, write the required mass balances and calculate the weight fraction of Na2SO4 in the mixer at the end of 10 min using 4th order Runge-Kutta Method by taking Δt= 0.5 min.

). A 15 wt% Na2SO4 solution is fed at the rate of 12 kg/min into a miser that initially holds 100 kg of a 50-50 mixture (by weight) of Na2SO4 and water. The exit solution leaves at the rate of 10 kg/min. Assume uniform mixing, which means that the concentration of the exit solution is the same as the concentration in the mixer. (a) What is the total mass in the mixer at the end of 10 minutes? (b) What...

Five hundred twenty kilograms of aqueous solution containing 185 kg of dissolved MgSO4 is fed to a crystallizer wherein 80% of the dissolved salt crystallizes out as MgSO4·6H2O. The solubility of MgSO4 in the solution leaving the crystallizer is 20 g MgSO4 per 100 g H2O. A. How many kilograms of the hexahydrate salt crystals are obtained from the crystallizer? B. How many kilograms of water is evaporated in the process?

Water flows through a shower head steadily at a rate of 8 kg/min. The water is heated in an electric water heater from 158C to 458C. In an attempt to conserve energy, it is proposed to pass the drained warm water at a temperature of 388C through a heat exchanger to preheat the incoming cold water. Design a heat exchanger that is suitable for this task, and discuss the potential savings in energy and money for your area.
