1. For a fluid sample with a 15 kg mass and a volume of 3 m, calculate the density,
specific weight, specific volume and specific gravity. Use water density (1000 kg / m3)
as a reference. Consider gravitational acceleration (g) to be 10 m/s2.
2. If you put a circular object with a mass of 50 g and a radius of 30 cm on top of the
fluid sample and the affected surface length was 50 cm. Calculate the pressure and
surface tension created by the object. Consider gravitational acceleration (g) to be
10 m/s2
