Water lost through leaked steam calculator

Use latent evaporation heat consistently with the energy loss basis, not an unrelated total steam enthalpy.

Units

m_{\text{water}} = \frac{Q_{\text{annual}}}{h_{\text{fg}}}

Calculator

Enter the values you know and leave one box empty. Calculate finds the empty one, the result or any input.

Given

m_{\text{water}} = \frac{48{,}000{,}000}{960} = 50{,}000

Symbol	Meaning	Unit
$m_{\text{water}}$	annual mass of evaporated water lost	lb/yr
$Q_{\text{annual}}$	annual evaporation heat attributed to lost steam	Btu/yr
$h_{\text{fg}}$	latent heat of vaporization at steam conditions	Btu/lb

Symbol	Meaning	Unit
$m_{\text{water}}$	annual mass of evaporated water lost	kg/year
$Q_{\text{annual}}$	annual evaporation heat attributed to lost steam	kWh/year
$h_{\text{fg}}$	latent heat of vaporization at steam conditions	kJ/kg

Results are estimates for study and screening. Check the inputs, units and assumptions before you use them for design, billing or contract decisions.
