a. Given the specific weight of water is 9.81 kN/m and the density of water is 1000 kg/m. Calculate the specific weight and density of kerosene in SI units if the specific gravity is 0.823. b. Consider the tank in Figure 1 containing mercury (sg = 13.54), water, benzene (sg = 0.879) and air as shown. Calculate the air pressure above the Benzene. 200mm 200mm 200mm Air Benzene Water Kerosene Mercury Figure 1 c. For the compound manometer shown in Figure 2, all fluids: benzene (sg=0.876), Kerosene (sg=0.823), mercury (sg=13.54), air (s.g =1.2) are at 25 C. Determine the pressure difference between point, B and A, (PA-PB). Mercury Benzene FOFLEO Air 40 cm Figure 2 600mm Water 14 cm
