# How to calculate temperature to maintain specific pressure in steam kettle

My friend and I are building a steam kettle with a turbine attached for a uni project. We've designed a system where we have a spherical kettle with a volume of 3.3 L. From the kettle, we lead the steam through a 10mm pipe to a steam turbine, which also has a 10 mm outlet. We heat the kettle by burning gas below it. We want to have roughly 2 litres of water in the boiler to start off with.

Before we do anything, we want to calculate what temperature we need to achieve a pressure of roughly 2 bars inside the boiler, but we're not sure where to start. We're not looking for an answer, but rather some pointers for where to start.

Googling will find you tables of vapour pressure vs temperature, for example there is one here. The vapour pressure is two bar at about $121$ºC and three bar at about $134$ºC.
