 The Balloon **Gross Lift** is the lift generated by the volume of Gas.  Hydrogen has a density of about 0.09 kg/cu m and air about 1.2 kg/cu m at normal atmospheric pressure - generating a lift of a bit over 1.1kg/cu m. Helium has a density of about 0.17Kg/cu m - generating a lift of a bit over 1.0Kg/cu m.   Subtract the **Balloon Weight** plus the **Payload** weight form the **Gross Lift** to give the //free lift//. The **Recommended Free Lift** gives a **Rate of Ascent** of 320m/min (a bit over 1000ft per minute).
