9) an experiment has been performed to determine the porosity of an unconsolidated sandpack. distilled water was poured into a graduated cylinder to a height h . fine sand of average grain size of 150 um was poured into the graduated cylinder to a height hy to form the sandpack. it was found that the water in the graduated cylinder rose to a height h2 after the sand was poured into the cylinder. a. derive the expression for the porosity of the sandpack in terms of h, and h2. b. given hı = 5 cm and h2 = 8 cm, calculate the numerical value of the porosity of the sandpack. c. what is your best estimate of the permeability of the sandpack? give a numerical answer and briefly outline how you made the estimate.

i say endangered speceis thats always fun

i would expect light rain in pittsburgh throughout the following 24 to 48 hours. the lower/falling weights in urban areas toward the west demonstrate that a low weight framework is moving from west to east toward pittsburgh. low weight frameworks are ordinarily connected with precipitation. the way that you don't see a major drop in temperature in the more western urban areas demonstrates the low weight framework is moving with a warm front, so just light rain would be normal. substantial downpours or progressively vicious climate is just typically connected with chilly fronts, where the warm air is pushed up and over a cool front quickly. this quickly rising air (convection) is what gives you heavier torrential downpours, and other conceivably serious weather conditions.

sediment layers stop spreading when they reach a barrier or they run out of sedimentary material. lateral spreading is the movement of gently to steeply sloping, saturated soil deposits caused by earthquake-induced liquefaction. i hope this . : )

just took the test the answer is b.
