PROBLEMS 1. Accumulation represents the change in mass in the reactor per change in time. For a constant-volume system, it can be simply formulated as ,dc Accumulation = V" dt (28.1) where V = volume and e = concentration. Thus, a mathematical formulation for accu- mulation is volume times the derivative of e with respect to t. Solution. Equations (28.1) and (12.1) can be used to represent the mass balance for a single reactor such as the one shown in Fig. 28.1: v de V = Qcin - Qc dt (28.2) Accumulation = inputs – outputs Equation (28.2) can be used to determine transient or time-variable solutions for the reactor. For example, if c = co at t = 0, calculus can be employed to analytically solve Gn = 50 mg/m², Q = 5 m'/min, V = 100 m², and co = 10 mg/m², Use Euler's method to find the solution of e from t= 0 to 40 s with a step size (h) of 10 s.

The composition of a liquid with suspended solid particles is generally characterized by the fraction of solid particles either by weight or mass, Cs, mass = ms/mm or by volume, Cs, vol = Vs /Vm where m is mass and V is volume. The subscripts s and m indicate solid and mixture, respectively. Develop an expression for the specific gravity of a waterbased suspension in terms of Cs, mass and Cs, vol.
a) Assuming the effluent from the pulp and paper plant has a daily discharge of 15 m3/s, calculate the daily loading values for TSS and BOD5. (Remember: Loading (kg/day) = Q (m3/s) x concentration (mg/L)) **don’t forget your unit conversions and show your work if you can Assume a BOD5 concentration of 10 mg/L, and a TSS of 20 mg/L.
QUESTION1 1.1 Name and explain three forms of density ?1.2 A mixture of two liquids of equal volume is made; the one has a relative density of 0.8 and the other a density of 980 kg/m3. What will be the weight of 2 500 liters?
A wastewater treatment plant worker spends her day checking wet wells. She is exposed to hydrogen sulfide in this confined space. The average temperature in the wet well is 25°C and the atmospheric pressure is 101.325 kPa. The recommended time weighted average air concentration for occupational exposure to hydrogen sulfide is 10 ppm (v/v). This concentration is based on an assumption that the individual is generally healthy and is exposed for 8 hours per day, 5 days per week, 50 weeks per year, over a working lifetime (that is from age 18 to 65 years). Assuming an average female body weight and inhalation rate over the working life of the individual, what is the lifetime (75 years) CDI?

3 A farmer has a 10-heactare maize farm. The maize is under “Fall Army Worm” attack. The farmer has to urgently control the attack using a chemical called AGENOX 221. Motorized sprayers with tank capacities of 15 litres each are to be used. The recommended concentration of the chemical is 2 ml/L and each full tank will cover ½ hectare. A 50-man team is engaged to control the attack. Using the above information and the assumptions given below: i. What volume of the chemical is required to cover the entire field to control the “Fall Army Worm” attack? ii. If each man covers an area of 25 m2 from one end of the field to the other, how many trips will each of them make to cover the entire field? Assume ach man moves in a straight line. Assumptions: 1. The 10 ha farm is considered to be a perfect square. 2. There is a 2.5 % loss of chemical due to the transfer to the sprayer tank.
