Find the pressure drop \(\Delta p\) across the pipe.

Consider a viscous fluid flowing through a circular pipe of radius \(R\) and length \(L\) . The fluid has a viscosity \(\mu\) and a density \(\rho\) . The flow is laminar, and the velocity profile is given by: advanced fluid mechanics problems and solutions
