A U-tube contains liquid of unknown density. An oil of density
770 kg/m³ is poured into one arm of the tube until the oil column
is 13.5 cm high. The oil-air interface is then 4.5 cm above the
liquid level in the other arm of the U-tube. Find the density of
the liquid.

Whenever organic matter is decomposed under oxygen-free (anaerobic) conditions, methane is one of the products. Thus, enormous deposits of natural gas, which is almost entirely methane, exist as a major source of fuel for home and industry. a. It is estimated that known sources of natural gas can produce 5600 EJ of energy (1 EJ = 1018 J). Current total global energy usage is 4.0 x 102 EJ per year. Find the mass (in kg) of known sources of natural...

A mixture of benzene, Napthalene, trichloroethylene and chlorobenzene were found in a groundwater plume. Consider the partitioning of these four compounds in a contaminated soil. Assume that the hydrocarbon mixture has contaminated the soil at an average of 0.09 liters of the mixture per cubic meter of soil. Considering the soil above and below the water table (ie. each cubic meter is 60% saturated with water by volume). The soil contains 0.75% organic carbon and has a porosity of 30%...

10. Write a one-page summary of the attached paper? INTRODUCTION Many problems can develop in activated sludge operation that adversely affect effluent quality with origins in the engineering, hydraulic and microbiological components of the process. The real "heart" of the activated sludge system is the development and maintenance of a mixed microbial culture (activated sludge) that treats wastewater and which can be managed. One definition of a wastewater treatment plant operator is a "bug farmer", one who controls the aeration...
