Review of fluid mechanics
W = mg(kN, lb)
r = m/V (kg/m3, slugs/ft3)
g = W/V
Sg (fluid) = gfluid/ gwater
g = 9.81 ft/sec2, gw = 9800 N/m3.
Open channel flow
V = Q/A
V= average channel velocity, Q= discharge, A = x-sec area
PE = WZ= mgZ
KE = mv2 = (W/g) v2
Force F = PA
Work done (Pressure energy) = Fxd = PAd = P(Ad) = P(Volume) = PW/ g
TE =WZ + (W/g)v2 + PW/ g
H = Z + v2/g+ P/ g
Z + v2/g+ P/ g = constant
Z1 + v12/g+ P1/ g = Z2 + v22/g+ P2/ g
Q1 = Q2 = Q3= ….
This is all about RG744 Fall semester 2013
GOOD LUCK ;-)
