You are designing a vehicle drive train system and you have an engine/EM with 100kW power.
Consider:
Vehicle has zero clutch and drive shaft losses.
Vehicle has only friction and churning losses
Vehicle has 5 speed transmission.
Vehicle has an open differential.
Vehicle is driving in a straight line.
Calculate the power at the wheel hub after friction losses in transmission.
Efficiency of different gears:
External Gearing 0.985
Planetary
0.98
Bevel
0.98
Windage Losses and Oil Churning
Approx. 15-20%
