Fluid Flow Flashcards
Why is fluid flow important?
Need to understand laws of fluid for machinery
Linked to rheology
Fluid pressure
Force acting on any point of a liquid and is equal in all directions
Head of pressure
Fluid dynamics
Most processes require liquid to be moved
Flow determined by principles of conservation and mass
Mass balance
Quantity of liquid entering and leaving processing equipment
Must be with bends and different diameter pipes
Energy balance
Changes in energy itsel are due to interchange with surroundings
Fluid potential energy
Quantity of work performed in returning to base level
Fluid Kinetic energy
Work performed in a fluid which is in motion coming to rest
Pressure fluid energy
Work performed when fluids under pressure is released
Energy lost to friction
Frictional resistance leads to energy loss
Bernoullis equation
Principle of conservation of energy
Can be applied to calculate
Flow rates for fluids passing through pipes of different diameters
Flow rates from a nozzle
Mechanical energy required of a pump to move fluid
