In fluid dynamics, the Hagen–Poiseuille equation is a physical law that gives the pressure drop in a fluid flowing through a long cylindrical pipe. The assumptions of the equation are that the flow is laminar viscous and incompressible and the flow is through a constant circular cross-section that is substantially longer than its diameter. The equation is also known as the Hagen–Poiseuille law, Poiseuille law and Poiseuille equation.
The governing equation is,
if the viscocity of the fluid is negligible then bernoulis equation also applicable
ReplyDeletei.e,
press head+velocity head+elevation head=0
is bernoulli applicable for both incmpressible and cmpressible flow??actually whilw deriving bernoulli we assume incompressible flow...bt bernoulli is cnservayion of mechanical energy..so thats why i am in doubt..
