Radius is directly proport: to viscosity & vessel length & invers: propt: to fourth power of radius..
My Qs is that how vessel length affect resistant??? can any one describe this in detail??

though not clinicaly important i thinks it is due to inherent friction of the system fluid rubbing against the walls .

Vessel length is directly proportional w/ vessel resistance. . The greater the length the greater resistance.Iif the length doubles, the resistance doubles or if the length decreases by 1/2 the resistance also decreases by 1/2.
Can correlate it w/ Poisseuille equation.

I agree with all of you. The longer blood vessel is, the more energy is lost due to friction along that vessel

what that mean energy loss leads to inc: resistance???

it is only the way how I memorise it that the longer vessel is - resistance is higher
