How to calculate internal energy of water

WebL is heat of fusion, it’s 333000 kJ/kg for the freezing point of water. To find heat of say water at 30 C going to steam of 110 C you would have this equation: Q = cm (100-30) + Lm + cm (110-100) First term is for liquid water, second term is for the energy required for all of it to change to gas, third is for steam. However, you still need work. Web15 dec. 2024 · The specific internal energy at the initial state (state 1) may be found from the thermodynamic tables for water at p1 = 5 bar and T1= 240 °C. Note that saturation temperature for liquid water at 5 bar is 151.86 °C; hence, the water must be in the superheated vapor region since T1is greater than the saturation temperature. Using the …
