Notes: *Fuel consumption rates: First number based on genset hours, second rate based on pump hours.
System 3 has two pumps, 63 L/H and 126 L/H. The 63-L/H pump always ran with the 126-L/H pump. The fuel use rate is based
on the hours of the 126-L/H pump. Fuel use estimates are based on Weldin and CRREL data. Other data provided by Dave
Mitchell and Terry Edwards of Weldin, Inc.
