Pollution Control Technologies – Coursework 1 Order Description Question 1. Assuming the Sun and all the planets behave as black bodies, and considering the following information given in the Table below: (i) Determine the Solar flux arriving at the Earth’s surface, given that the temperature of the Sun is 60ooK. Subsequently, determine the Earth’s effective temperature, Te. (ii) Discuss the possibility of a greenhouse effect for the planets given in the Table. Planet Distance from the Albedo CO2 T (K) at Name Sun (km) (a) concentration ground level Venus 8 0.75 700 1.08 x 10 Mars 8 0.15 0.95 220 2.28 x10 Earth 8 0.3 1 X% 28 8 1.5 x10 5 78 ,2 ,4 Sun’s radius : 6.96x10 km; Stefan-Boltzmann Constant s = 5.67x10 W m K Question 2. (a) Calculate the total mass of the Earth’s atmosphere given that at the Earth’s surface, the atmospheric pressure is: P(0) = 105 Pa, and that the radius of the Earth is RE=6400 km. (b) Calculate the mass of emitted carbon since pre-industrial times, given that the concentration of Co2 has risen from 278ppm to 398 ppm. You may assume: (i) that the molecular weight of Carbon is 12 g/mole and (ii) overall molecular weight of air and the atmospheric mass have not been modified since pre-industrial times. Question 3. A power plant burns 970 tons of coal (containing 2% sulphur) per day. All of the sulphur is burned completely and emitted into the atmosphere from a stack with an effective height of 102 m. For a wind speed of 5.2 m/s, atmospheric stability category C, calculate SOZ concentration at: (a) the ground level along the plume centre line, 10 km downwind; (b) 5 m above ground, 3 km downwind, at central line.
