Dear Hemin

Simply, you can get this information from the steam tables with a known temperature to decide the corresponding pressure.

http://www.thermopedia.com/content/1150/

Regards,

Abdelhalim abdelnaby Zekry

The pressure required to boil the water at specific temperature lower than its normal boiling temperature at one atmospheric pressure of 100 degree centigrade is given in the table in the link:http://www.jbind.com/pdf/Cross-Reference-of-Boiling-Temps.pdf
