A piston of surface area 1200 mm² moves inside a cylinder

A piston of surface area 1200 mm² moves inside a cylinder with a velocity of 6 m/s. The piston has a diameter of 50 mm and the cylinder has a diameter of 50.2 mm. The space between symmetrically positioned piston and cylinder is filled with lubricant of coefficient of viscosity 2.5 x 10^-2 Pa.s. What is the power loss (in watts)?
