6.3 Contamination of vegetable oil
Vegetable oil is used in a food processing factory to prepare instant breadcrumbs. A stirred tank is used to hold the oil.
During operation of the breadcrumb process, oil is pumped from the tank at a rate of 4.8 1 h-¹. At 8 PM during the
night shift, the tank is mistakenly connected to a drum of cod liver oil, which is then pumped into the tank. The volume
of vegetable oil in the tank at 8 PM is 60 1.
(a) If the flow rate of cod liver oil into the tank is 7.5 1h-1 and the tank has a maximum capacity of 100 1, will the tank
overflow before the factory manager arrives at 9 AM? Assume that the density of both oils is the same.
(b) If cod liver oil is pumped into the tank at a rate of 4.8 1 h 1 instead of 7.5 1 h−1, what is the composition of oil in
the tank at midnight?
6.1 Dilution of sewage
In a sewage treatment plant, a large concrete tank initially contains 440,000 litres of liquid and 10,000 kg of fine
suspended solids. To flush this material out of the tank, water is pumped into the vessel at a rate of 40,000 1 h −1.
Liquid containing solids leaves at the same rate. Estimate the concentration of suspended solids in the tank at the end of
5 h. State your assumptions.
6.13 Heating glycerol solution
An adiabatic stirred tank is used to heat 100 kg of a 45% glycerol solution in water. An electrical coil delivers 2.5 kW
of power to the tank; 88% of the energy delivered by the coil goes into heating the vessel contents. The glycerol
solution is initially at 15°C.
(a) Write a differential equation for the energy balance.
(b) Integrate the equation to obtain an expression for temperature as a function of time.
(c) Assuming glycerol and water form an ideal solution, how long will the solution take to reach 90°C?

- This is a tilt and rotation question. Here are notes attached for reference. I prefer handwritten solutions. ONLY UPLOAD A SOLUTION IF YOU ARE SURE ABOUT THE ANSWER PLEASE. I prefer handwritten solutions.arrow_forwardConsider a constant area semi-infinite fin of a circular cross section of radius r. and thermal conductivity k. The base is maintained at T. and the surface of the fin exchanges heat by convection to an ambient fluid at T with a heat transfer coefficient h. It is desired to increase the heat transfer from the fin. The following suggestions are made: (i) doubling k, (ii) doubling ro, (iii) doubling h. Which suggestion will bring about the largest increase in heat transfer? To x h, T C A h, Tarrow_forwardA 20 cm long 304 stainless steel bar is initially at 18°C.
