A hydrometer consists of a spherical bulb with a cylindricall stem (figure below). The cross-sectional area of the stem is 0.54 em2. The total volume of bulb and stem is 13.6 cm3. When immersed in water, the hydrometer floats with 8 em of the stem above the water surface. In alcohol, 1 em of the stem is above the surface.

98 *°* When the hydrometer of Problem 48 (Figure 13-34) is placed in a liquid whose specific gravity is greater than some minimum value, the device floats with part of the glass tube above the liquid level. Consider a hydrometer that has a spherical bulb 2.4 cm in diameter. The glass tube attached to the bulb is 20 cm long and has a diameter of 7.5 mm. The mass of the hydrometer before lead pellets are dropped into the bulb...

30 in weighs 0.042 lbf in air. Consider the A hydrometer with a stem diameter following: 1) Determine the submerged volume (ft) when the hydrometer floats in water (y = 62.4 lbfift? Calculate the submerged volume (ft) when the hydrometer floats in ethylene glycol (SG = 1.12). Evaluate the height (in.) above the free surface where the 1.0 mark resides when the hydrometer floats in ethylene glycol. 111)

A hydrometer is an instrument used to determine liquid density. A simple one is sketched in the figure below. The bulb of a syringe is squeezed and released to let the atmosphere lift a sample of the liquid of interest into a tube containing a calibrated rod of known density. The rod, of length L and average density rho_0, floats partially immersed in the liquid of density rho. A length h of the rod protrudes above the surface of the...

A U-tube with a cross-sectional area of 1.00 cm2 is open to the atmosphere at both ends, Water is poured into the tube until the water rises part-way along the straight sides, and then 5.00 cm3 of oil is poured into one end. As a result, the top surface of the oil ends up 0.550 cm higher than the water surface on the other side of the U. What is the density of the oil?

A cylindrical container with a cross-sectional area of 61.2 cm2 holds a fluid of density 816 kg/m3. At the bottom of the container the pressure is 120 kPa. Assume Pat = 101 kPa. Depth of the fluid = h=2.37m Find the pressure at the bottom of the container after an additional 2.05×10−3 m3 of this fluid is added to the container. Assume that no fluid spills out of the container.
