The porosity lab experiment started with a brief info session about the usage of the various equipment (Gas porosimeter, Electronic Balance, Caliper) and gases such as helium gas. For the labwe conducted the method of using measured bulk volume (Venier Caliper). The procedures for this lab include: 1. Weigh the dry sample using the electronic balance and record it weight, Wd. 2. Open the jaws of the caliper and take three lengths readings of the core plug at three diferent locations. Calculate their average, Lavg, and record the data. 3. Measure the diameter five times, each one at different location. Calculate the average diameter, Davg, and record the data. 4. Before using the Gas Porosimeter, calibrate it by placing all valves in
