separate cream from dairy milk and coconut milk. 2. To measure the quantity and density of cream and skim milk. MATERIALS : Dairy milk powder and coconut milk. APPARATUS : 25 ml specific gravity (SG) bottles‚ 1 L beaker‚ thermometer. PROCEDURES : Clean the machine ↓ Assemble machine ↓ Switch on machine ↓ Pour sample into feed receptor ↓ Collect cream & skim ↓ Record the quantities (skim and cream) ↓ Measure density (cream and skim) using SG bottle. DISCUSSION : In this experiment

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

Using the formula for density‚ D=mass/volume‚ 47.4 g/ml was obtained. For the specific gravity‚ the formula SG=density of the liquid/density of water‚ and .79 was

Student Instructions: Why does a hot air balloon float even though it is so heavy? Hot air balloons float because the buoyancy force of the hot air is more than the weight. Buoyancy occurs because the hot air has a lower density than the cooler outside air. This lower density air weighs less than the air it replaces and that difference is the buoyancy. What makes balloons float when they are full of air but not float when they are deflated? Balloons float when they are full of hot air because

tanks to raise density and allow the submarine to sink and it also pumped out to reduce density and hence allow the submarine to float. The tanks can be filled with water and air‚ which allows the submarine to sink or rise in the water. When a submarine is floating‚ its ballast tanks are filled with air‚ which makes it less dense than the sea water it displaces hence allowing it to float. Submarines sink when water is let into the ballast tank. This is because the submarine’s density becomes greater

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

experiment is all about buoyancy and density. Buoyancy describes whether objects float or sink. Usually describes how things float or sink in different gasses. Density deals with the amount of mass an object has. Adding salt to the water adjusted the water. Squeeze the bottle hard enough‚ putting pressure to the packet. This causes the bubbles to get smaller and the entire packet to become more dense. Objective: The objective of this experiment is to find the density and buoyancy which is an upward

Principle: Cyclone desander is based on the principles of centrifugal sedimentation and density difference‚ when the water under a certain pressure from desanding into the equipment by the inlet to tangential‚ it will come about a strong rotation‚ due to the different density of sand and water‚ under the common action of the centrifugal force‚ centripetal force‚ buoyancy and fluid drag force‚ make the low density water rising‚ and expel from the outlet‚ the dense sand will be discharge outlet from

distinguished French chemist‚ created a relatively simple method for determining the molecular mass of a volatile substance. In this experiment we will use a modified version of his technique to determine the molecular mass of an unknown volatile liquid. The density of a gas is given by the ideal-gas equation as‚ Dgas = m PM = V RT where M is the molecular mass of the gas. Solving for molecular mass‚ we obtain: € M= mRT PV Thus‚ the molecular mass of a gas can be determined by measuring the
