1.a well is contaminant with 340 mg/L of tetrachloride ( perchloroethylene) . the water must be remediated to achieve a concentration of 0.2 mg/L ( the detention limit ). Design a packed tower strpping column to meet this requirement using the following design parameters.
2.Water at a pressure of 13 atm, at street level, flows into a building at 3m/s through a 6 cm diameter pipe. The pipe tapers down to a 2 cm diameter by the top floor 50 m above. The density of water is 1,000 kg/m^3. Calculate the water pressure and velocity on the top floor?
3.Explain how heat is transfered from one oject to another and describe how the construction of a Thermos Bottle prevents this transfer?
