4. An insulating brick (true specific gravity=2.58) weighs 3.90lb dry, 4.77lb saturated in kerosene, and 2.59lb suspended in kerosene (specific gravity =0.82 ). Calculate the open porosity, apparent density, bulk density, and closed porosity. Answer: 0.4;152.3lb/ft3=2.44g/cm3;91.55lb/ft3=1.46g/cm3;0.0323
