  7. Diffusion is spreading out of molecules due to random thermal motion of the molecules and is characterized by molecules behaving as 'random walkers'
  8. Pumps provide head to the fluid so that it can be transferred from one place to another. It does not pressurize the fluid, It simply transfers momentum. It is used for liquids as well as gases at low pressure and high volume. Compressor: as the name suggests,it has the ability to compress gas and then the valve opens to deliver the gas at that pressure. It is used for gases at high pressure and low volumes such that it pressurizes the gas inside the device body. It provides pressure energy to the fluid. Thus every compressor is a pump but every pump is not a compressor.
  9. Difference between convection and radiation

    Convection occurs between a solid object and a fluid which is in motion through the warmer part of the fluid. Natural convection occurs due to density difference in the molecules of fluid due to temp. Gradient. Forced convection occurs due to forced motion of the fluid through external force such as fam,pump ,moving object etc. Radiation occurs through the electromagnetic waves. It does not require a medium for transport of energy

  24. What is meant by hindered settling?

    settling at reduced velocity due to interactions with other particles.
  25. Baffles create turbulence in the flow of shell side fluid in heat Exchanger hence increasing the rate of heat transfer.but baffles create pressure drop in heat Exchangers.hence they must be designed such that pressure drop doesn't exceed the allowable pressure. Supports the tubes and prevent them for sagging in long heat Exchangers..also reduce vibrations in heat Exchangers.
