5. Compute a linear least-squares-fit of the calibration data and plot the resulting line on the same graph as the calibration data. Comment on the linearity of the pressure transducer and scannivalve. Part 3: Calibration of the Tunnel 1. Connect the micromanometer (calibrated in Part 2) across the wind-tunnel contraction in order to measure the static pressure drop.
Some of the environmental issues related to hydraulic fracturing must be investigated and regulations must be put in place. As a nation dependent on energy we must regulate and consider all consequences before allowing the depletion of yet another natural and non-renewable resource. Environmentalists claim an array of issues related to fracking. Polluted groundwater and aquifers, micro seismic events, disposal of waste water and the mining of the silica sand which is used in the process are all by-products of a loosely regulated practice. Studies have been done, from measuring the effects on drinking water to monitoring seismic events related to fracking.
Finally, we analyze the errors in both parts of the lab by propagation by substitution and compare the theoretical-experimental values using errors. III. Results: The theoretical buoyant forces for the sphere, the small cylinder, the block, and the big cylinder are 0.297N, 0.131N, 0.369N, and
This colligative property is important in many industries, but is clear to see when using ordinary salt to remove ice from steps or a driveway. The water takes salt into solution, which in turn lowers the freezing point of the water, ensuring that even sub-freezing ambient temperatures do not lead to ice buildup anywhere the salt or ice melt was applied. Experimental Procedure: Before any measurements were taken, equipment was set up and calibrated. Using Microlab’s integrated calibration file the thermistor was calibrated in order to obtain accurate temperature measurements. A graph for the data was also set up with time on the x axis in .5 second intervals and temperature on the y axis.
Ghostbuster Slime Lab 10/4/2012 Abstract The purpose of this experiment was to observe the physical properties and changes of the creation of a polymer as a result from cross-linking. A borax solution was made and was combined with a polyvinyl alcohol solution. A polymer’s cross-links give them many properties, like bonding ability, elasticity, and viscosity. The amount of water added in the experiment directly affected the viscosity and elasticity of the slime polymer. Too much water added resulted in a high viscosity and low elasticity.
Introduction: In this lab there were several purposes. Each purpose was to help further the class’s understanding of thermodynamics. Thermodynamics studies the changes in chemical and physical reactions and how energy influences those changes. The purposes of the lab were to decided which of the four given substances would make a good hot pack or cold back, to be able to design a hot pack and cold pack for specified temperature changes, to calculate the amount of heat released or absorbed by one gram of calcium chloride or ammonium nitrate, and to calculate the percentage error in the experiment. In order to understand the lab one must also understand endothermic and exothermic reactions.
Since Bitumen is very heavy and viscous it must be treated so it can be refined and used. There are many oil sands
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
The extended holding of the waste fluid in the pits could lead to their seepage into the ground, especially if the pits are not lined with plastic. This contaminates the water sources around. In addition, any overflows, for instance caused by heavy rains, allows the fluid to contaminate water in the sources. Large volumes of fluid is required (thousands of gallons of water is used per well) and its disposal is an issue too (Schmidt, 2011). Proper disposal methods should be effected to ensure the water aquifers around do not get contaminated.
Whereas health is concerned more with disease causing situations. Another definer is that safety is focused on accidents that are acute (sudden and severe). Health is focused on less intense but more prolonged issues (chronic) that can cause problems through poor design. With that is mind, Zackowitz and Vredenburgh (2008) state that human factors practitioners are used to design systems and products to aid in the reduction of human errors. This is traditionally done at the early design stage, but they are often required to analyse system failures to understand why an event has occurred.
