Answer / prateek jha

Flow Rate is usually used in industries working on
hydraulic and pneumatic areas to specify the amount of
working fluid passed across a fixed cross-section areas in
fixed time. Mostly, we describe flow rate in Litre Per
Minute means how much litres of working fluid has been
passed through a given cross-section area in One minute.
Flow Rate is independent of pressure in
hydraulic i.e liquid. but is dependent on pressure in gases
as gases are compressible at pressure. Hydraulic is also
compressible but at higher pressure.
