I use this list for building my formulas in html on this site
g = Earths gravity= 9,81 [m/s2]
y = Pressure Head [m]
r saltwater = 1025 [kg/m3]
p = Pressure [Pa=N/m2]
DH1-2 = Head losses [m]
F = Newton Force [N]
A = Area on which the force acts [m2]
A = Wetted Area [m2]
A = Wetted Area [m2]
Q = Discharge/ flow rate [m3/s]
u = Velocity [m/s]
v = Mean velocity [m/s]
v = Mean velocity [m/s]
V1 = Mean velocity before [m/s]
V2 = Mean velocity after [m/s]
m = Weight [Kg]
g = Earths gravity= 9,81 [m/s2]
y = Pressure Head [m]
z = Potential Head [m]
u2
— = Velocity Head [m]
2·g
D = Hydraulic Diameter = 4·R [m]
R = Hydraulic Radius = D/4 [m]
u = Kinematic viscosity [m2/s]
u water 20°C = 1,00·10-6 [m2/s]
m = Absolute viscosity [kg/ms]
m water 20°C = 1,00·10-3 [kg/ms]
m water 20°C = 1,00·10-3 [kg/ms]
r = Density of liquid [kg/m3]
r fresh water = 1000 [kg/m3]r saltwater = 1025 [kg/m3]
p = Pressure [Pa=N/m2]
b = Width orifice [m]
h1 = Pressure at top orifice [m]
h2 = Pressure at bottom orifice [m]
Cv = Velocity coefficient (0,97-0,99) [1]
Cc = Contraction coefficient (0,61-0,66)[1]
h = Pressure just before orifice [m]
Sf = Slope hydraulic gradient caused by friction [1]
ks = Surface roughness [m]
hf = Frictional head loss [m]
L = Length [m]
hf = Frictional head loss [m]
L = Length [m]
Nice information is shared here. I was looking for blogs Fluid Mechanics Lab Equipment , then I found this blog, this is really nice and interested to read. Thanks to author for sharing this type of information.
