Bouyant force: Pressure at depth in fluid: Pressure in a hydraulic cylinder:
laminar flow
- a type of fluid flow where a liquid or gas moves in parallel layers, without mixing or disruption between the layers
- “streamlined”
- molecules move together, no big/changing gaps turbulent flow
- little vortices
- speed of fluid / magnitude & direction is constantly changing
continuity equation (relates cross sectional area to velocity at different points) for non-compressible fluid: for compressible fluid volume flow rate
viscosity
- velocity of fluid near edges of pipe will be much slower than in middle of pipe flow rate
- integral over area
mass flow rate: Burnoulli’s equation
