A block with specific gravity of SG= 1.45 and volume V= 0.75m3, is attached to a spring scale. The block is hung vertically such that it is fully submerged in oil ρoil= 0.85kg/m3 . a) Draw a free body diagram for the block. b) What is the apparent weight of the block?

1. A dam as shown in Figure Q.1 is to be built to hold 256 m³ of water. The curved surface of the dam has a shape prescribed by the relation y=x. If the width of the dam is 8 m, determine: 5 m Water Level Dam h b Figure Q.1. Schematic of the proposed dam. i) the height (h) of the dam, and ii) the resultant hydrostatic pressure force acting on the curved surface. Take density of water as 1000 kg/m³

The plastic block shown below measures l.5 m x/.S m x(.7 m and has a specific gravity of 0.38. The concrete block B (density = 2400 kg/m) is suspended from the corner of the plastic block by means of a cable and the plastic block is thus floating in the lake (T = 15°C) in the orientation shown. Determine the volume of the concrete block (units of liters) noting that it does not rest on the bottom of the lake, Neglect the weight and volume of the cable in your analysis. %3D %3D 1.7 m 0.5m Water Cable B

Find the height of the portion of a cubic block that extends below the water surface (h) , the specific gravities of block and seawater are given to be SG = 0.778 and 1.025, respectively. h1 = 13.1cm

Fluid Mechanics & Machinery Q-5b A fluid has specific gravity of 0.9. What is the value of specific weight? (Take g = 10 m/s²).

When a hydrometer (see the figure below and in the Video) having a stem diameter of 0.30 in. is placed in water, the stem protrudes 3.15 in. above the water surface. If the water is replaced with a liquid having a specific gravity of 1.09, how much of the stem would protrude above the liquid surface? The hydrometer weighs 0.042 lb. h = Hydrometer- Fluid surface in.
