MFSacedon Study of Fluids

MFSacedon Fluids in Motion Topics: Fluid flows Continuity equation Bernoulli ‘s Energy Equation

MFSacedon IDEAL FLUIDS is incompressible(density cannot change) and no internal friction (called viscosity) Flow line – path of individual particle of moving fluid Steady flow – flow pattern does not change with time. Flow tube – flow lines passing through the edge of an imaginary element of area Laminar flow -

MFSacedon Laminar flow Turbulent flow

MFSacedon Laminar flow A 1 v 1 = A 2 v 2 ρ 1 A 1 v 1 = ρ 2 A 2 v 2 for incompressible fluids for compressible fluids

MFSacedon A 1 v 1 = A 2 v 2 The product Av is the volume flow rate dV/dt (volume flow rate)
