Absolute Pressure
the difference between the measured pressure and a vacuum
New cards
4
Gauge Pressure
the difference between measure pressure and atmospheric pressure
New cards
5
Eureka
states that the buouant force on a submerged object is based upon the weight of the displaced fluid

Definition of Pressure P = F/A
F = force in Newtons A = surface area in m2
New cards

Density roe = m/V
V = volume in m3 m = mass in kg
New cards
8
Pressure in a Static Column of Fluid (at any point in the fluid) P = P0 + (roe)gh
P = pressure in pascals P0 = pressure acting on surface of the fluid roe = density in kg/m3 g = acceleration due to gravity h = height of the column of fluid above the point where pressure is being determined

Buoyancy Force Fb = (roe)Vg
roe = density of displaced fluid in kg/m3 V = volume of displaced fluid in m3
A = cross sectional area of pipe or flow tube in m2 v = fluid velocity in m/s V/t = volumetric flow rate in m3/s m/t = mass flow rate in kg/s roe = density of fluid in kg/m3
