Hydrogen Energy

Energy is a quantity that cannot be defined, its existence can only be felt. In simple language, if a system possesses energy, it can do a specific kind of work. There are many forms of energy sources which people can use to obtain work. Solar energy, tidal energy, hydroelectric energy, geothermal energy, wind energy are some of the renewable energy sources which are primarily used for the production of electricity.

Question

A 20,000 L tank of water with pH of 7.5 is to be treated with a liquid hydrogen bromide acid
(HBr). If after 5000 L of the acid was added to the volume in the tank the pH becomes 5.5, how
much mass of hydrogen was added to the system? How much total HBr was added?

The alkalinity of a water sample at pH 7 is 300 mg/L as CaCO3. Calculate the molar concentration of bicarbonate (HCO3-). Note that because the pH is less than 8, you can assume that all of the alkalinity is in bicarbonate form. Your Answer:
You are asked to design a disinfection process using chloramine as your disinfection agent. The influent concentration of giardia is 1000 organisms per 100 ml. The USEPA regulation requires a 3 log reduction in giardia concentration in the disinfection process. The chlorine contact tank is 30 meters long and has a cross section area of 10 square meters and the flowrate is 150 cubic meters per hour and can be modeled as a plug flow reactor. The Ct value that needed is 1100 mg/L min. It is important to know that the chloramine concentration breaks down over time due environmental factors that are beyond your control. The decay is a first order process and has a decay coefficient of 0.1 hr-1. What is the effluent giardia concentration? In order to ensure disinfection occurs we often use the effluent concentration in our Ct calculation, what is the effluent concentration of chloramine? Given the decay behavior of chloramine described above, what concentration of chloramine should I dose…

You are treating 10 million gallons per day (MGD) of water with alum at a dosage of 50.0 mg/L. Alum is available as a hydrated salt Al2(SO4)3.16H2O. Determine:(a) The monthly alum dosage required in metric tons/month (1 metric ton = 1000 kg)(b) If you assume that each equivalent of alum added to the water consumes 1 equivalent of alkalinity, determine the alkalinity consumed by alum addition in milliequivalents/L (meq/L)(c) Given that the raw water contained 30 mg/L as CaCO3 of alkalinity, is the alkalinity sufficient? What would happen if the alkalinity is inadequate?

A separator accepts waste oil at 70% oil and 30% water by weight. The top product stream is pure oil while the bottom underflow contains 10% oil. If a flow of 20 gal/min is fed to the tank, how much oil is recovered? Two methanol-water mixtures are contained in a separate flask.

Design a laboratory scale chemostat to aerobically treat a 10 liters per day of a synthetic wastewater containing 500 mg/L of glucose. In order to design and operate such a chemostat you will need to not only need to calculate the volume of the reactor, but you also need to determine the amount of oxygen that must be supplied and at what rate, and the amount of biomass produced and the composition of the effluent (i.e., effluent COD and biomass concentration). Make reasonable assumptions for all necessary parameters you may need for this problem. Make sure to check units of parameters assumed.
A liquid delivery system is being designed such that ethylene glycol flows out of a hole in the bottom of a large tank. The designers need to predict how long it will take for the ethylene glycol to completely drain. Since it would be very expensive to run tests with a full-scale prototype using ethylene glycol, they decide to build a one-quarter scale model for experimental testing, and they plan to use water as their test liquid. The model is geometrically similar to the prototype as shown in the Figure.(a) Temperature of the ethylene glycol in the prototype tank is 60°C, at which υ = 4.75x10-6 m2/s. At what temperature should the water in the model experiment be set in order to ensure complete similarity between model and prototype?(b) The experiment is run with water at the proper temperature as calculated in part (a). It takes 3.27 min to drain the model tank. Predict how long it will take to drain the ethylene glycol from the prototype tank.
