A good geothermal well produces 75 kg/s of hot water at 200°C. For the same amount of delivered energy, what would the production rate be from an oil well? How does this compare with a typical US oil well producing about 100-1,000 bbl of oil per day? You can assume that the average heat capacity of the geothermal water is 4,200 J/kg K and that the minimum useful temperature is 50°C and that crude oil has a heating value of about 5.5 million Btu per bbl.
What is the pH of a buffer prepared by mixing 57.4 mL of 0.050 M sodium bicarbonate and 10.2 mL of 0.10 M NaOH. (Carbonic Acid: pKa1 = 6.35, pKa2 = 10.33)
Consider the reaction with the rate law, Rate = k[BrO3-][Br-][H+]2 By what factor does the rate change if the concentration of BrO3- is tripled and that of Br- is tripled? Just put in the number as a whole number or fraction.
