Answer to Question 1

5 x 1 = 5inches for vertical lift 20/10 = 2 inches for horizontal run 5+2=7 inches vacuum

Answer to Question 2

Superheating the refrigerant leaving the evaporator insures that no liquid enters the compressor. If liquid does enter the compressor it can be damaged because liquid is non-compressible.
