biological substances occur as mixtures of different components in the gas‚ liquid‚ or solid phase. In order to separate or remove one or more of the component from its original mixture‚ it must be contacted with another phase. The two-phase pair can be gas-liquid‚ gas-solid‚ liquid‚ or liquid-solid. Absorption When the two contacting phases are a gas and a liquid. A solute A or several solutes are absorbed from the gas phase into a solid phase. Distillation A volatile vapor phase and a

Show that the temperature of the gases along a cylindrical exhaust pipe is given by the following expression: hπ d T − Tw = (To − Tw ) exp − x mC & p where Tw is the wall temperature assumed to be constant along the pipe‚ To is the gas temperature at the inlet to the exhaust pipe‚ h is the convective surface heat transfer coefficient‚ d is the diameter of the pipe‚ m is the mass flow rate of the exhaust gasses‚ Cp is the mean specific heat of the exhaust gasses‚ x is the distance

Sound A. What is the definition of Sound? Sound is everything that a person‚ animal or computer can hear. It can be created in a countless number of ways and occurs from anything as simple as tapping on a table. All sounds are a series of vibrations that travel through a medium in all possible directions. The cause of sound is the vibration of an object; once the item vibrates the sound waves then radiate outwards until they are either stopped or they die out. A sound wave has three characteristics:

have a greater distance apart from each other than the particles between a solids and a liquid 2) why are gasses considered fluids? Gasses are fluids because they are able to flow 3) what’s happens to gas particles when a gas is compressed? When a gas is compressed it will move gas particles closer and make the volume smaller. 4) what is the difference between force and pressure? Force is the pressure applied to an object. Pressure is moved when something moves. 5) what’s is the

that this relation becomes: This relation is useful because‚ in order to obtain a value for we need to calculate it relative to some other value (i.e.‚ a reference state). If we consider the simplest case that we can think of‚ that is an ideal gas‚ we can rearrange‚ substitute and integrate where the values refer to whatever the reference state is chosen to be. There are two issues with this: • there is not a simple choice of what the reference state should be • at low (zero) pressure

confined space some of the liquids will evaporate. Evaporation of the liquid depends on the strength of the intermolecular forces that are between liquid molecules. During the evaporation process of the liquid‚ new gas molecules exerts pressure in the sealed container‚ while some of the gas condenses back to the liquid state. If the temperature inside the container is kept constant‚ then the equilibrium at some point will be reached. When the equilibrium is reached‚ the rate of condensation is equal
