stream. The pressure drop for the
cold stream is calculated using Equation
(20):
Here:
L = 32 ft ≅ 9.80 m (see the section
above, Calculate the length of the heat
transfer plate)
ρ = 62.35 lbm/ft3 = 998.85 kg/m3
(Assumption 1.10)
V = 10.70 ft/s = 3.26 m/s (see the section
above, Calculate the film heat
transfer coefficient of the cold side)
AT
FISH AREN'T450°C
THE ONLY

FRY.
Determine the outside spiral diameter.
The diameter of the outside spiral
is determined via Equation (21):
Ds = [15.36L (Sh + Sc + 2t) + C2]1/2
Here:
L = 32 ft (see the section above,
Calculate the length of the heat
transfer plate)
Sh = 1.25 in. (Assumption 1.1)
Sc = 0.25 in. (Assumption 1.1)
t = 0.125 in. (Assumption 1.1)
C = 12 in. (Assumption 1.1)
Then:
Ds = [15.36L (Sh + Sc + 2t) + C2]1/2
= [15.36(32)(1.25 + 0.25 + 2(0.125)) +
(12)2]1/2
Ds = [491.52(1.75) + 144]1/2 =
[1,065.6]1/2 = 31.69 ⇒ Use 32 in.
The results are shown in Table 1. ■

Graphite oxidizes at high
temps. So gaskets made with
graphite deteriorate as well.
,
the revolutionary
sealing material
from Flexitallic
maintains its
integrity up to
982º C. Preventing
leakage and the loss
of bolt load that can
be so costly-and
ultimately dangerous.
Replace your graphite
gaskets because when
the heat's on, graphite is
out of its depth. Visit:
