WebThis tutorial considers basic desuperheating theory and calculations. Superheated steam is steam that is at a temperature higher than the saturation temperature for the steam pressure. For example, steam at a pressure of 3 bar g has a saturation temperature of 143.762°C. If further heat were to be added to this steam and the pressure remained ... WebMar 4, 2024 · 1 Answer. You simply need to keep your signs straight. By convention, work done by the system (e.g., turbine work) is considered positive and work done on the system (e.g., pump work) is considered negative. In the case of heat, heat into the system is positive and out is negative. With these conventions, the first law is. banderas de guatemala png
