According to this formula, the theoretical slope is 1.250 (m/kg) and the y-intercept is found to be -0.050 (m).

4) Using the new values of am recalculate the new values for bm . (1)

The steps were repeated except only went up by increments of 20 mL. Trend Statement: The slope is consistent through the end four points where the line increases at a more rapid rate. The Y intercept is

Equation 7 is equation 6 rearranged to solve for the missing variable Vi. From equations 6 and 7 Mi is the initial molarity and Vi the initial volume. Mf is the final molarity and Vf the final molarity.

2004). To interpret seismic data in terms of hydrate content, a relationship between hydrate saturation in the pore space of sediments and elastic velocity is necessary. Lee et al. (1996) developed a weighted equation model, in which hydrate is considered as a part of the pore fluid. However, this model is not based on physical principles and requires empirical calibration. The velocities predicted from the cementation theory proposed by Dvorkin and Nur (1996) are much higher than those normally observed in nature (Ecker et al. 1998). In 1999, Helgerud et al., introduced an effective

• When working through this equation, make sure all of your units are in the proper metric form:

To calculate the volume of the metal bar in the geometric method, it was assumed that the bar was a perfect trapezoidal bar; however, this was not the case. The cross-section of the bar was slightly round, most notably on the long side of the trapezoid. This means that the geometric method was not able to accurately estimate the volume of the sample. Additionally the geometric method requires 4 measurements to be taken with a ruler. This provides more opportunity for inaccuracies in the measurement method to arise.

This formula used the points (2, 14.5) and (7, 14.0). Then, just substitute the slope for m and the y-intercept, or 14.7, for b. This gives you the formula t= -0.1w + 14.7. However, Ryan’s information is given in a table:

Item 4: Application for USGS solid methods. A second PT study was analyzed and submitted to WVDEP by Phenova on 07/08/2016. Both studies (R17601 closed 6/17/16 and R17949 closed 7/8/16) show the laboratory obtained acceptable results.

Out in the field, some testers interpolate a compaction curve to represent the material using the Alberta Family of Curves. One of the goals of this applied research, was to test the accuracy of this method. It was concluded that the only true way to verify the legimitacy of this curve is by doing index testing such as atterberg limits and grain size analysis on the soil. The City of Edmonton does require the testing firm to do a standard proctor and atterberg limits on each soil type on a project. A true maximum dry density and optimum moisture content can be obtained only by doing a standard proctor in the lab. Furthermore, the liquid limit and plastic limit values can give the tester a better idea on how much moisture variance is acceptable for the material. In case the Alberta Family of curves must be used to quickly obtain a compaction curve in the field, having a classification of the soil using atterberg limits and grain size analysis will provide the tester with backup information to interpolate a more reliable compaction curve.

The answers provided by the formula X = -b / 2a are exactly the same as the answers given for the

10. The seismic reflection coefficient R for the interface between two layers of rock is given (approximately) by the following equation for normal incidence (sound raypaths hit the interface between two rock layers at a right angle), where ρ1 is the density of layer 1 (top), ρ2 is the density of layer 2 (bottom), v1 is the velocity of sound in layer 1 (top) and v2 is the velocity of sound in layer 2 (bottom):

The MATLAB code generated was quite basic, the program aimed to easily calculate the required variables through firstly finding the pole locations using the MATLAB built in abs

(c) Explain the difference between point loads and uniformly distributed loads. Include annotated pictorial diagrams

This residual graph shows a very distinct pattern, which is identified by the curved displacement of the points. The points start declining and fall below the trend line, only to curve at the bottom and increase back above the trend line. Due to the strength of this pattern, an
