6. A working area of a mine has diesel equipment operating within it. The maximum diesel loading is 750 kW. The same section of the mine also has a methane inflow of 0.25 m³/s flowing into it. If the maximum permissible methane concentration in the general body of the air is 0.5% and the design diesel air quantity is 5 m³/s per 100 kW of installed diesel power, determine the required ventilation flow rate for the working area.

A 1000 litre containment tank catches the outflow from a processing apparatus which has 800 litres of water with 2g of chemical agent dissolved in it. Additional supply comes into the tank at 3 litres/hr containing 5 g/litre of the chemical agent. The solution leaves the containment tank at 3 litres/hr. When the amount of chemical agent in the containment tank reaches 500 g, no more supply is allowed to enter the system. Instead,fresh water is input into the tank at 2 litres/hr; and at the same time,the outflow is increased to 4 litres/hr. How much chemical agentis held in the containment tank at any time t.Assume all liquids are well-mixed.
