#1ST LAW OF THERMODYNAMICS CALCULATOR GENERATOR#
Power Out = Energy Out * Generator Efficiency.Energy Out = ( Inlet Specific Enthalpy - Outlet Specific Enthalpy) * Mass Flow.Step 4: Calculate Steam Turbine Energy Out and Generation (Power Out)
Using the outlet specific enthalpy, calculate the outlet properties:
Outlet Specific Enthalpy = Inlet Specific Enthalpy - Isentropic Efficiency * ( Inlet Specific Enthalpy - IDEAL Outlet Specific Enthalpy). Quality of Energy: A heat engine produces reversible work. ( Inlet Specific Enthalpy - Outlet Specific Enthalpy) Thermodynamics calculator for solving mixing problems. A thermodynamic process is only possible if it satisfies both the 1st and 2nd laws simultaneously. Isentropic Efficiency * ( Inlet Specific Enthalpy - IDEAL Outlet Specific Enthalpy) =. What you need to know is that energy transformations always result in losses to waste heat. As shown in Figure 12. 12.6 Here, U is the change in internal energy, U, of the system. Thermal energy has the most disorder, or the most entropy. In equation form, the first law of thermodynamics is U Q W. Entropy is the amount of disorganization present in a system. Step 3: If solve for 'Outlet Properties', Determine Outlet Specific Enthalpy The second law of thermodynamics states that entropy increases every time energy is forced to reroute or change forms. ( Inlet Specific Enthalpy - IDEAL Outlet Specific Enthalpy) Isentropic Efficiency = ( Inlet Specific Enthalpy - Outlet Specific Enthalpy) /. Using the outlet specific enthalpy, calculate the isentropic efficiency: 
Step 3: If solve for 'Isentropic Efficiency', Determine Outlet Properties Step 2: Calculate Ideal Outlet Properties (Inlet Entropy equals Outlet Entropy) Its the first law of thermodynamics and one of the most fundamental, and most often used equations in all of thermodynamics. This is a way to calculate the internal energy. Youd have to plug in a negative value for the work here. Inlet Energy Flow = Specific Enthalpy * Mass Flow If the piston moves up, thats negative value of the work done on the gas.The Specific Enthalpy is then multiplied by the Mass Flow to get the Energy Flow: Calculation Details Step 1: Determine Inlet Properties Using the Steam Property Calculator, properties are determined using Inlet Pressure and the selected second parameter (Temperature, Specific Enthalpy, Specific Entropy, or Quality).
