Viscous Fluid Pressure Drop in a Pipe

Very Hard Physics Fluid Mechanics

A cylindrical pipe with a radius of 0.1 meters is used to transport a viscous fluid with a dynamic viscosity of 0.5 Pa·s at a flow velocity of 2 m/s. If the length of the pipe is 10 meters, what is the pressure drop along the length of the pipe due to viscous effects?

Assume the flow is laminar and use the Hagen-Poiseuille equation for your calculations.
