some heat and the hot water losing some takes place‚ before they both exit the exchanger. What is actually happening is‚ the hot water is heating either the inside or the outside of the tubes in the exchanger‚ depending on where it is flowing‚ by what is known as convection. Then the heat is conducted through the tubes to the other side‚ either the outside or the inside‚ where it is then convected back into the cold water raising its temperature.

Centrifuge is an instrument which can spin carrier vessels at high rotation speed and very high centrifugal force to allow centrifugation. The centrifugal force generated is proportional to the rotation rate of the rotor and the distance between the rotor centre and the centrifuge tube. There are three general classes of centrifuges: low speed‚ about 5000 rpm‚ high speed machine
