Large blooms of algae result from high nutrient loading in rivers and lakes, for example, as a result of runoff of fertilizers from agricultural fields. When the algae die, they biodegrade and consume oxygen. The amount of oxygen consumed is called the biochemical oxygen demand (BOD). If the level of oxygen dissolved in water becomes too low, fishes become stressed and susceptible to viral or bacterial infections. In severe cases, fish kills result. A simplified empirical formula for algae is C6H15O6N.
a) Write a balanced chemical reaction for the conversion of 1 mole of algal cells tocarbon dioxide, water and ammonia (NH3).
b) Calculate the theoretical BOD of algae (g BOD/g algae).
CHE 352 – Spring 2014, In this assignment, students will review some of the concepts of measurements discussed, 4 methods of measuring temperature, 4 methods of measuring fluid pressure
Adsorption and Membrane Processes
Implications of the future of fabrication for international trade, transportation, and logistics
Piston arrangement: compressing air, A piston arrangement has been developed to compress air adiabatically from 360C
Determine the energy needed to quench a hot gas with water, Assume we have a 100,000 cubic foot per minute gas (air) stream at 700 degrees F that goes to an air pollution control device
Calculate the molar fraction of the system in the vapor phase
The atmospheric pressure of 100k Pa acts on the other side of the piston. The gas is heated until the volume is doubled and the final pressure is 500 kPa. Calculate the work done by the gas.
Eliminate Differences in composition and eliminate differences in temperature, pressure and phase
Using the information in the above table to show how the specific volume of each liquid varies with temperature. You should plot a graph for each liquid and use this graph to estimate the exact value of a at 50°C for each liquid.
Equal rates of mass transfer for the production of the fine chemical are required. This is often required for certain types of organic synthesis.
Develop a series of design graphs that can be used to demonstrate acceptable combinations of tubes dimensions
The pressure of a sample of gas at a constant temperature of 25 degrees C is increased from 1.0 atm to 1.2 atm. If the original volume was 3.8 liters, what will the new volume be?
