SOME APPLICATIONS OF DIFFERENTIATION 313
G
is the pressure difference between the ends
of the tube,ris the radius of the tube,L
is the length of the tube andηis the coef-
ficient of viscosity of the liquid.ηis obtained
by measuring Q,p,r andL.IfQcan be
measured accurate to±0.5%,paccurate to
±3%,raccurate to±2% andLaccurate
to±1%, calculate the maximum possible
percentage error in the value ofη.
