displaced fluid remains valid. The weight of the displaced fluid is directly proportional to the volume of the displaced fluid (if the surrounding fluid is of uniform density). In simple terms‚ the principle states that the buoyancy force on an object is going to be equal to the weight of the fluid displaced by the object‚ or the density of the fluid multiplied by the submerged volume times the gravitational acceleration‚ g. Thus‚ among completely submerged objects with equal masses‚ objects with greater

and analytical balances. b. How did you do it? Briefly describe the procedures in 1 sentence. We calibrate a volumetric pipet and flask. We also calibrated a beaker and 50 mL buret. We also calculate the difference between the expected density and density obtained by our team. c. What happened? Briefly give the result (or results) of the experiment in 1 sentence. We noticed the calibration marks on the beakers were taken only to be an approximate guide to volume because the marks were placed

A group of investors wants to develop a chain of fast-food restaurants. In determining potential costs for each facility‚ they must consider‚ among other expenses‚ the average monthly electric bill. They decide to sample some fast-food restaurants currently operating to estimate the monthly cost of electricity. They want to be 90% confident of their results and want the error of the interval estimate to be no more than $100. They estimate that such bills range from $600 to $2‚500. How large a sample

deeper under the sea the density of the water does not change‚ and this means that if the submarine’s buoyancy is less than its weight at one depth it will also be less than its weight at any other depth‚ and so‚ unless other forces are involved‚ when water is let into the air tanks the submarine will sink right to the bottom of the sea no matter how deep it is. A submarine is kept level at any depth by maintaining a balance between the air and water. The submarine’s density must be equal to the surrounding

PERMEABILITY HOMEWORK Problem 1: Assume a vertical cylindrical core filled with water. The length of the core is 1 feet and its radius is 1/12 ft. Water density is 62.428 lb-mass/ft3 and water viscosity is 1 cp. We wish to inject additional water into the bottom of the core and flow water from bottom to top through the core where the top of the core is exposed to the atmosphere‚ i..e.‚ the pressure at the top of the core is 14.7 psi. What is the minimum pressure required at the bottom of the core

This paper presents the results of an investigation into the effect of the breadth of the particle size distribution on the flow function‚ bulk density and internal friction of four food grade fillers namely; lactose‚ dextrose‚ maltodextrin and sodium chloride. Physical property measurements‚ including particle size and particle shape‚ are presented along with bulk flow properties which were measured
