A core sample of basalt, 4 inches long and 2 inches in diameter, was tested in unconfined compression. The basalt is known to have a modulus of elasticity = 9.1 x 106 psi.
a) At a pressure of 10,000 psi, what would be the reduction in length of the sample?
b) At this pressure, what would be the vertical load on the sample?
c) At 10,000 psi stress the core showed an increase in diameter of 5.5 x 10-4 inches. What is the Poisson’s ratio for this sample?
Plot the concentration of tracer at the outlet of the each of the two reactors during the first 24 hours of the tracer study. (Hint: You may need to use mass balances to obtain equations that predict the concentration of tracer as a function of time)
The base line vector between the base and roving reciever is 8340m and has an accuracy of +/-(1to 2 cm +/-2ppm). What is the estimated uncertainty in the length of this vector
