EXAMPLE:

 

 

UNIT SIZE _________________042

 

 

Entering Water Temp. _____160°F

 

 

Entering Air Temp. ________ 40°F

 

 

Water Temperature Drop ____ 10°F

 

 

 

I. CAPACITY @ 20° TD:

Read output directly from Table 35 & Table 36,

 

A. For 200° EWT, 60° EAT

22,700 BTU/HR (Ref., Std. 042, p. 12).

 

 

 

 

B. For EWT and/or EAT above or below

Multiply output from Table 35 & Table 36 by factor from

22,700 x .878 = 19,931 BTU/HR.

Standard

Table 38.

 

 

 

 

II. CAPACITY AT OTHER TD's

Multiply output obtained in IA. or IB.

IA - 22,700 x 1.15 = 26,105 BTU/HR.

A. For TD's from 5 to 60°F

(above) by appropriate factor from Table 39

-OR-

 

 

IB - 19,931 x 1.15 = 22,921 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 35 & Table 36 by appropriate factor from Table 39

2.34x 2.30 = 5.38 GPM (Applies only to units with. Std. 200° EWT, 60° EAT.) For all others calculate using formula - GPM = BTU/500 x TD

IV. PRESSURE LOSS AT OTHER TD's

Multiply P.D. of unit for 20° TD, from Table 35 & Table 36 .06 x 5.00 = .30 Ft. H2O
