Steam Conversion Tables - Example Calculations
Conversion factor example #1:
•
•
•
• Maximum mounting height
Solution:
•
• Air temperature rise conversion factor is 1.40, from Table 11.1.
•
• The mounting height correction factor is 0.86, from Table 12.1.
•
•
• The maximum mounting height at standard conditions is 20 feet, from Table 13.1.

Conversion factor example #2:
be the actual capacity and rate of condensate production for the selected unit?

From Table 13.1, a V 139
The capacity of the V 139 at actual conditions will be Btu

Alternate Solution:
Low Outlet Temperature models are normally recommended for steam pressures above 30 lb. However, the use of these
models with steam pressure less than 30 lb. is acceptable.
Based on the example above, a V 161L
at standard conditions.
The capacity of the V 161L at actual conditions will be Btu
