Hlm = [K(Qlateral/D2)2/2g][0.1669]
EQUATION (IP):
(11)
or
Hlm = [K(Qlateral/D2)2/2g][1,586.7]
EQUATION (SI):
where
Hlm
=
head loss through total hose length from
ship deck riser to pier riser, ft (kPa)
K
=
loss coefficient for fitting at
lateral/main intersection
For each ship in
the berthing plan, determine the
number of 50-foot (15.2-m)
hose lengths and total hose length
required to reach from the
inboard ship deck discharge riser to
the pier riser. Determine
the head loss through the hose
lengths by Equation 12.
Hh = (f[L/D][Qbilge/D2]2)/g
EQUATION (IP):
(12)
or
Hh = [(f[L/D][Qbilge/D2]2)/g] [79,217]
EQUATION (SI):
where
Hh
=
head loss through total hose length from
ship deck riser to pier riser, ft (kPa)
L
=
total hose length from ship deck riser to
pier riser, ft (m)
Qbilge
=
flow rate of one bilge pump, gpm (L/s) (see
Table 11)
D
=
diameter of oily waste transfer hose, in.
