A tube of length l and radius R carries a steady flow of fluid whose density is p(rho) and viscosity n(eta). The fluid flow velocity depends on the distance r from the axis of the tube as v = v0 (1 - r^2/R^2). Find (a) the friction force exerted on the tube by the fluid (b)the pressure difference at he ends of the tube???

(a) part can be solved by finding (eta)A dv/dr at r=R and (b) part can be obtained by using Poisueille's Equation for an elemental cylindrical layer of radius r and with dr... then integrate it for finding the total flow rate to be taken in the equation... that will give your pressure difference which will be same for all elemental layers...

Sir I want to know that whether your books provide material only for mains and olympiads or advanced.if not or yes after solving physics galaxy it is better to follow cengage or sri balaji or IE irodov
