This program computes the saturation steam pressure as a function of temperature using the equation of Keenan, Keyes, Hill, and Moore. It will run using either Fahrenheit or centigrade and provides an output in saturation pressure measured in megapascals (MPa [10^ 7 dynes/ cm ^ 2]) and pounds per square inch absolute (PSIA).

Program Notes:
The program is designed to run with the following parameters:
Maximum temperature
(F) 705.44
(C) 374.15
Minimum temperature
(F) 32.00
(C) 0.00

Test Case:
Determine the operating pressure of a steam boiler at 220°F.
 

SATURATION STEAM PRESSURE


FAHRENHEIT OR CENTIGRADE {F/C}?  F

INPUT TEMPERATURE (32-705 F) = 220

PRESSURE -MPA  = 0.11850669
PRESSURE -PSIA = 17.188085
