4. A 1000 litrecontainmenttankcatches the outflowfrom a processing apparatus whichhas 800 litresof water with2 gof chemical agentdissolved in it.  Additional supplycomesinto the tank at 3 litres/hr containing5 g/litreof the chemical agent. The solution leaves thecontainmenttank at 3 litres/hr. When the amount of chemical agentin the containment tankreaches 500 g, no more supplyis allowed to enter the system. Instead,fresh water is input intothe tank at 2 litres/hr; andat the same time,the outflow is increased to 4 litres/hr.  How much chemical agentis heldin thecontainmenttankat any time t.Assume all liquids are well-mixed.(10marks

A 1000 litre containment tank catches the outflow from a processing apparatus which has 800 litres of water with 2 g 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...

Water vapor at 800 lbf/in.2, 1000 F enters a turbine operating at steady state and expands adiabatically to 2 lbf/ in.2, developing work at a rate of 490 Btu per lb of vapor flowing. Determine the condition at the turbine exit: two- phase liquid–vapor or superheated vapor? Also, evaluate the isentropic turbine efficiency. Kinetic and potential energy effects are negligible.

The intermediate product of a chemical process is a chemical paste that is saturated with water....
The intermediate product of a chemical process is a chemical paste that is saturated with water. The paste is rolled into a thin layer and placed to dry in a flat area 30m long 15m wide. Drying is enhanced by blowing hot air over the paste, and the mass transfer coefficient is 0.017 m/s. Diffusion of water through the paste is rapid so that the concentration of water vapor at the surface of the paste remains constant at 0.002 gmol/L....

An emergency breathing apparatus often placed in mines or caves works via the following chemical reaction: 4KO2(s)+2CO2(g)→2K2CO3(s)+3O2(g) If the oxygen supply becomes limited or if the air becomes poisoned, a worker can use the apparatus to breathe while exiting the mine. Notice that the reaction produces O2, which can be breathed, and absorbs CO2, a product of respiration. What minimum amount of KO2 is required for the apparatus to produce enough oxygen to allow the user 30 minutes to exit...

1. Electrolytic reactions, like other chemical reactions, are not 100% efficient. In a copper purification apparatus depositing Cu from a CuSO4 solution, operation for 5.47 hours at a constant current of 5.45 A deposits 29.2 g of Cu metal. What is the efficiency? b) How long would it take to electroplate all the Zn2+ in 0.280 L of 0.210 M ZnSO4 solution with a current of 2.35 A? please answer both A and B

Q1/GDebi Enterprises is thinking of building a chemical processing plant to produce 4-hydroxy-3-methoxybenzaldehyde. The firm estimates that the initial cost of the project will be $14.6 million, and the plant will produce cash inflows of $7.2 million for the next 5 years, after which time the project will terminate. In the 6th year however, the firm will need to clean up the site, which it estimates will cost it $4.9 million. The discount rate the firm wants to use for...
