Mass fraction calculator

The mass fraction is a measure used in chemistry and other scientific fields to express the proportion of one substance (the “component”) in a mixture relative to the total mass of the mixture. It is a dimensionless quantity expressed as a ratio or percentage. Mathematically, the mass fraction (w) of a component in a mixture […]

Adiabatic efficiency of turbine calculator

The adiabatic efficiency of a turbine is a measure of how efficiently it converts the enthalpy drop of the working fluid into mechanical work under adiabatic conditions (no heat transfer). It is typically denoted by the symbol  ηad​ and is given by the ratio of the actual work done by the turbine to the ideal

Entropy change for isothermal heat transfer calculator

Entropy change for an isothermal heat transfer process refers to the change in entropy that occurs when heat is transferred between two systems at constant temperature. In such a process, the temperature of the systems involved remains constant throughout the transfer. The entropy change (ΔS) for an isothermal process is given by the ratio of
