When a hydrometer 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 1.19, how much of the stem would protrude above the liquid surface? The hydrometer weighs 0.042 lb .
A hydrometer consists of a spherical bulb with a cylindrical stem (figure below). The cross-sectional area of the stem is 0.59 cm2. The total volume of bulb and stem is 13 cm. When immersed in water, the hydrometer floats with 8 cm of the stem above the water surface. In alcohol, 1 cm of the stem is above the surface. Find the density of alcohol. 8.0 cm 1.0 cm water
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.

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...
Compare the floating of hydrometer in a diet cola with a regular soft drink How could the hydrometer be modified to increase A large tub of ice and water holds cans of both regular and diet pop. Some cans some don What can you surmise regarding their content? POST-LAB Questions 1. Compare the floating of a hydrometer in a diet cola with a regular soft drink. How could the hydrometer be modified to increase accuracy? A large tub of ice...
A U-tube contains liquid of unknown density. An oil of density 770 kg/m³ is poured into one arm of the tube until the oil column is 13.5 cm high. The oil-air interface is then 4.5 cm above the liquid level in the other arm of the U-tube. Find the density of the liquid. A raft is made of 11 logs lashed together. Each is 38.0 cm in diameter and has a length of 7.00 m. How many people (whole number)...
Many people have imagined that if they were to float the top of a flexible snorkel tube out of the water, they would be able to breathe through it while walking underwater. However, they generally do not consider just how much water pressure opposes the expansion of the chest and the inflation of the lungs. Suppose you can barely breathe while lying on the floor with a 370 N weight on your chest. How far below the surface of the...
Please answer this problem FULLY with detail steps on how to slove. My professor normally has us answer these questions by hand, and for complex imformation to put the rest into Excel. So, the handworked steps and solutions would be greatly apprecited. Thank you! For the following problems you must develop a diagram to show the situation, include a brief problem statement and clearly show the energy balance equations you are using (start from the appropriate form of the energy...

10. Write a one-page summary of the attached paper? INTRODUCTION Many problems can develop in activated sludge operation that adversely affect effluent quality with origins in the engineering, hydraulic and microbiological components of the process. The real "heart" of the activated sludge system is the development and maintenance of a mixed microbial culture (activated sludge) that treats wastewater and which can be managed. One definition of a wastewater treatment plant operator is a "bug farmer", one who controls the aeration...
