Problem: A truck powered by a diesel engine working at a 100% load factor is operated at a mine. If fuel consumption for this truck is 0.3 l/kW and the truck is rated at 1,200 kW what is the level of fuel consumption per hour and the cost of fuel per hour for the following conditions:
a) Load factor low = 0.2
b) Load factor medium = 0.35
c) Load factor high = 0.6
Assume cost of diesel is $ 0.25 /l.
