A load bauxite has a density of 3.15 g/cm3. If the mass of the load is 135.5 metric tons how many dump trucks, each with a capacity of 12 cubic yards, will be needed to haul the whole load.         Use the equivalents: 1MT = 1 x 10 3 kg, 1 yd = 3 ft, 1 in = 2.54 cm

A U-tube manometer is connected between two pipes as shown below. One pipe contains carbon tetrachloride at 13 kPa gauge, while the other pipe contains oil at 172 kPa absolute. Determine the height, h, in mm. Assume barometer reads 0.9 atm. Carbon tetrachloride SG = 1.6 4m Oil SG 0:8 h

5. A long, solid cylinder of radius 2 ft and length 6 ft is hinged at Point A is used an automatic gate. The weight of the cylinder is 8600 lbf. When the water reaches certain height (h), the cylindrical gate opens by tuning about the hinge at point A. Determine h. " 2 2Ft
