Speeds for max range and endurance

[ATP_Al]

I'm dusting off my performance notes in preparation for an interview with a turboprop operator. It's been a while since i've looked at the books so i've got a few questions:

(1) Do the speeds for pistons apply to turboprops as well?

(2) I understand that the speed for best range in a piston is the tangent to the power required curve. My notes also say that this speed coincides with the minimum drag speed, Vmd. So where on the drag curve is minimum power speed, Vmp, and why do you need less power at this speed even though drag is higher?

Thanks,

Al
