    The centrifugal pump is an extremely simple machine It is a member of a family known as rotary machines and consists of two basic parts 1 the rotary element or impeller and 2 the stationary element or casing volute The figure below is a cross section of a centrifugal pump and shows the two basic parts VOLUTE IMPELLER Figure 1Procedure for using centrifuge Before use check the inside of the centrifuge and the rotors to ensure that everything is dry If there is any sign of corrosion discontinue use until the corroded part has been repaired by a qualified service technician

    basic principles and terminology Drying is a complex operation involving transient transfer of heat and mass along with several rate processes such as physical or chemical transformations which in turn The Basic Principles of Sieve Analysis Introduction Many natural and manufactured materials occur in a disperse form which means that they consist of differently shaped and sized particl The particle size distribution ie the number of particles of different sizes is responsible for important physical and chemical properties such as

  • ADVERTISEMENTS Read this article to learn about the basic principles of sedimentation and also about sedimentation coefficient Basic Principles of Sedimentation The rate of sedimentation is dependent upon the applied centrifugal field G being directed readily outwards this is determined by the square of the angular velocity of the rotor ω in radians s 1 and Working with Centrifug JoVE Cambridge MA Principl A centrifuge consists of three basic parts a rotor a drive shaft and a motor 2 The rotor holds the tubes bottles or bags containing the liquids to be centrifuged It is usually made of a high strength material such as

  • Working with Centrifug JoVE Cambridge MA Principl A centrifuge consists of three basic parts a rotor a drive shaft and a motor 2 The rotor holds the tubes bottles or bags containing the liquids to be centrifuged It is usually made of a high strength material such as Centrifugation definition Centrifugation is the process that uses centrifugal force for the separation of two liquids in a mixture In this process denser component of the mixture migrates away from the axis and lighter component migrates towards the axis The process of centrifugation is carried out in a centrifuge as shown in Fig 7
