Table 30. Hot Water Calculations and Correction Factors S Type
EXAMPLE:
UNIT SIZE: __________________ 024
Entering Water Temp. _______ 160°F
Entering Air Temp. ___________ 40°F
Water Temperature Drop _______ 10°F
I. CAPACITY @ 20° TD:
A. For 200° EWT, 60° EAT
Read output directly from Table 29, 17,400
BTU/HR (Ref., Std. 024)
B. For EWT and/or EAT above or below
Standard
Multiply output from Table 29 by factor from
Table 31
17,400 x .878 = 15,277 BTU/HR.
II. CAPACITY AT OTHER TD's
A. For TD's from 5 to 60°F
Multiply output obtained in IA. Or IB. (above)
by appropriate factor from Table 32
IA-17,400 x 1.15 = 20,010 BTU/HR.
-OR-
IB-15,277 x 1.15 = 17,569 BTU/HR.
III. GPM AT OTHER TD's
A. For TD's from 5 to 60°F
Multiply GPM of unit for 20° TD, from
Table 29 by appropriate factor from Table 32
1.8 x 2.30 = 4.14 GPM (Applies only to units
with Std. 200° EWT, 60° EAT.) For all others
calculate using formula-GPM = BTU/500 x TD
IV. CAPACITY AT OTHER RATES OF
WATER FLOW
Multiply output from Table 29 by factor from
Table 34.
V. PRESSURE LOSS AT OTHER TD's
A. For TD's from 5 to 60°F
Multiply P.D. of unit for 20°TD, from Table 29
by appropriate factor from the Table 32
.014 x 5.00 = .07 Ft. H
