Question

Research on how a hydrometer is used and answer the problem. The hydrometer shown sinks 5.3 cm in water (15°C). The bulb displaces 1.0 cm2, and the stem area is 0.1 cm2. Find the weight of the hydrometer.

0.1 cm?

= 5,3 cm

F = 1.0 cm

2. A freshly cut log floats with one-fourth of its volume protruding above the water surface. Determine the specific weight of the log.

3. A body, with a volume of 2 ms, weighs 40 kN. Determine its weight when submerged in a liquid with SG = 1.59.

4. An object is constructed of a material lighter than water. It weighs 50 N in air and a force of 10 N is required to hold it under water. What is its density, specific weight, and specific gravity?

5. A wide barge 3m wide by 8m long by 2m deep weighs 20 kN empty. It is proposed that it carry a 250-kN load. Predict the draft in (a) Fresh water (b) Salt water (SG = 1.03)

ELABORATE
Solve for the following buoyancy problems.
A= 0.1 cm?
1. Research on how a hydrometer is used and answer
the problem. The hydrometer shown sinks 5.3 cm in
water (15°C). The bulb displaces 1.0 cm3, and the
stem area is 0.1 cm?. Find the weight of the
hydrometer.
2 = 5.3 cm
= 1.0 cm3
2. A freshly cut log floats with one-fourth of its volume protruding above the
water surface. Determine the specific weight of the log.
3. A body, with a volume of 2 m3, weighs 40 kN. Determine its weight when
submerged in a liquid with SG = 1.59.
4. An object is constructed of a material lighter than water. It weighs 50N in
