4. (a) Calculate the permeability of a core sample to a liquid using the following information: q=0.0143 cc/sec, u = 0.685 cp, L = 2.43 cm, A = 2.66 cm, AP = 144.7 cm distilled water. (b) Calculate the permeability of the same core sample to air using the following information: 9 = 7.184 cc/sec, u =0.0184 cp, Patm = Po = 72.95 cm Hg, AP = 73.4 cm Hg
