I am going through a textbook and working on problems without a professor, so I don't really have anyone to ask when issues come up. The textbook is "Manufacturing Automation" by Yusuf Altintas. You can try to find a pdf of it online, or there is a version you can flip through here:

The question I am struggling with is given below (but you probably won't be able to figure it out without looking at the rest of the book):
A twist drill with a diameter 2R = 19.05 mm, chisel edge angle ψc = 125◦, chisel width 2w = 0.78 mm, and nominal helix angle of β0 = 30◦ is used in drilling a titanium alloy Ti6Al4V. Predict the thrust, torque, and power of the drilling operation when the drill feed and spindle speed are c = 0.1 mm/rev and n = 200 rev/min, respectively. Use the orthogonal cutting parameters of Ti6Al4V given in Table 2.1.
My problem is with Problem 6 in Chapter 2 (found on page 65). I just feel like they don't give me enough information to solve the problem, like I don't know what the taper angle of the drill is, or what
