Specific Enthalpy of Water Vapor Solution

Follow our step by step solution on how to calculate Specific Enthalpy of Water Vapor?

FIRST Step Consider the formula

h dry = 2500 + 1.9 \cdot t db

Next Step Substitute values of Variables

∴

h dry = 2500 + 1.9 \cdot 110

Next Step Prepare to Evaluate

∴

h dry = 2500 + 1.9 \cdot 110

Next Step Evaluate

∴

h dry = 2709000J/kg

LAST Step Convert to Output's Unit

∴

h dry = 2709kJ/kg
