On the other hand,small difference at the exhaust end becomes of great the same time, when high vacua are considered, the workingtemperature must be very low. This diagram also shows very prominently the energy avail-able in steam above and below atmosphere. It has been demon-strated that the turbine in this low pressure range is very ef-ficient and it is now being extensively used as a low pressure orexhaust steam turbine.
