Studies have been done, from measuring the effects on drinking water to monitoring seismic events related to fracking. While the validity and interpretation of these studies can be brought under scrutiny depending on the viewpoint of the respective group, the mining of the required silica sands and the damages it is ensuing on the environment must be taken into
Then, a well is vertically drilled from the surface into the ground, and then horizontally to the point that access to the target rock containing the gas is possible. A steel pipe is then inserted into the well. The pipe must have pores on some part that will access the deeper level containing natural gas to allow the fracking fluid to flow out of the pipe to react within the target zones, (Schmidt, 2011). The pores form the route through which the gas will flow into the well and up to the surface as well as the flow of the fracking fluid back to the surface. The volume of the fracking fluid ejected through the pores exceeds the volume of the same that penetrates to the target zones.
Osmotic pressure, one of the colligative properties previously discussed, is defined as the pressure used by the water flow through a membrane separating two solutions with different concentrations of various solutes. The purpose of this lab was to assist in the educating one upon the freezing points of a pure solvent compared to that of a solvent found within a nonvolatile solute, while at the same time understanding and gaining a greater depth of osmosis. I greatly enjoyed this lab, although I wish it could have been conducted in less time. Observations: I took note of several components of the lab conducted. The dialysis tubing was one I especially monitored, checking every hour with recordings.
Tanker Test 1.) Hauling liquids in tankers requires special care for two reasons. One reason is the _______ center of gravity that tankers have.-High. 2.) You need to be extremely cautious when driving smooth bore tankers.
There are many different cleaning agents which will be used in different places and circumstances. Household detergent and hot water remains the most effective method of removing contamination, bleach should be used on blood spills on hard surfaces. A COSHH assessment is needed for any cleaning
To get the right result for solution reaction to occur, it is base on the measuring liquid for each solution. You need to pour the right amount of each solution so you can determine the result of solution reaction (product) will occurs accurately. If you pour your solution (liquid) into a beaker not at the right point than you can’t find the result of solution reaction (product) accurately. You need to put a lid on top of a weighing bottle because you don’t want your solution to spill out and other stuff (oil, dirt, sweat) will get into a weighing bottle that can cause the mass is not accurate and not
2.2 Cleaning agents should be used to prevent infection and to follow any organisational policies and COSHH regulations. Cleaning agents include soap-based detergents and can be used for floors, walls, fixtures and fittings and persons. 2.3 Disinfecting agents generally include chemical detergents that are antibacterial or antiseptic and are used for the disinfections
Find the molarity is essential to numerous amounts of future procedures such as equivalent weigh. The titration of hydrochloric acid was also completed for practice of titrating and basic understanding of the characteristics of the strong acid. In all three titration experiments an indicator was used to illustrate the
The cross section helped to better understand the thickness, flow direction and distribution of the aquifer(s) within the mapping area. 3 river stream gages are placed in the stream in order to better understand the relationship between groundwater and surface water by giving quantities of discharge/recharge in cubic feet per second (cfs). Understanding the relationship between the groundwater and surface water gives aid for producing the potentiometric surface map which includes the gaining (effluent) and losing (influent) parts of the stream. Results Two aquifers were located, a confined and unconfined aquifer. The unconfined aquifer, or the upper aquifer, (see cross and contour map) consists of a predominately sand rich and partial gravel unit and is approximately 50 feet thick.
This makes it possible to equate the expansion of the reservoir fluids upon pressure drop to the reservoir vodage caused by draw of oil, gas, and water minus the water influx. Successful application of this method requires an accurate history of the average pressure of the reservoir. As well as reliable oil –gas and water –production data and (PVT) data on the reservoir fluids, if sufficient pressure and production performance data are recorded and (PVT) data describing the reservoir fluid behavior is available. The amount of oil or gas in place in a reservoir sometimes may be the computed by material balance
