Hydrostatics and Fluid Dynamics Flashcards
Density Equation
p = m/V
Weight Equation
F = pgV
Pressure equation for fluids with uniform density in a sealed vessel
P=pgz
Absolute Pressure Definition and Equation
absolute pressure in a fluid due to gravity somewhere below the surface is given by the equation
P=Po +pgz
Gauge Pressure Equation
Pg= P - Patm
Hydraulic Systems Equations
F1/A1 = F2/A2
A1d1 = A2d2
Pascal’s Principle
A change in the pressure applied to an enclosed fluid is transmitted undiminished to every portion of the fluid and to the walls of the containing vessel
Work in a Hydraulic System Equaiton
W= F1d1 = F2d2
Archimedes Principle Equation
F(bouy) = p(fluid)gV(submerged)
If the Weight of the fluid displaced is less than the objects weight the object will
sink
If the weight of the fluid displaced is greater than or equal to the objects weight then it will
float
Bernouli’s Equation Deffinition and Equation
P + 1/2 pv^2 + pgh = constant
Used in Venturi Flow Meters and for fluid flow
