ettolrach Posted January 23, 2019 Share Posted January 23, 2019 Right now, atmosphere pressure is measured in kilogrammes. As far as I understand, the maximum pressure can vary depending on what substance there is (since it's the mass that's displayed). For example, natural gas geysers will stop working at 5 tonnes, while oxygen diffusers stop at 2 tonnes (again, as far as I understand). Changing the displayed unit will also allow for better calculations. For example, you can figure out how much gas you would pump into a room to heat it to a specific temperature by using (P1 V1) / T1 = (P2 V2) / T2 where P = Pressure, V = Volume, and T = Temperature. So if I keep the volume constant and want to increase the temperature from 20 °C to 40 °C and start with a pressure of 75 kPa, I'd need to do: 20°C = 293 K, 40°C = 313 K P1 / T1 = P2 / T2 75E3 / 293 = P2 / 313 255.97... = P2 / 313 P2 = 255.97... * 313 P2 = 80 119.45... P2 = approx. 80.1 kPa Link to comment Share on other sites More sharing options...
badgamer123 Posted January 24, 2019 Share Posted January 24, 2019 actually if you put oxygen making machine in 5kg Nat gas they will stop working...they game don't count for real pressure,I hear someone said it drain too much computing power that way.

[...] Sorry, but the ideal gas law does not apply. Temperature is completely orthogonal to pressure/density in ONI. You do not get pressure-based phase changes, there is no triple point, and even thermal conductivity rules change drastically between open gas, gas in pipes, gas vs. liquids vs. solids, etc. You can math ONI, but you cannot really science it. It's a game, and simplifying rules have been implemented for performance considerations. Link to comment Share on other sites More sharing options...
cpy Posted January 24, 2019 Share Posted January 24, 2019 Just look at stationeers, with barely anything in game they simulate pressure and small base can tax 10 threads on 9900K @ 100% Just saying. Link to comment Share on other sites More sharing options...

Well, you can science it too, you just have to approach it with the understanding that the laws you know and the laws it operates under are different.
