The head loss of a water of kinematic viscosity 1x10^-6 m^2/s in a 50mm diameter pipeline was 0.25m over a length

of 10 m at a discaherge of 2L/s. What is the corresponding discharge and hydraulic gradient when oil of kinematic viscosity 8.5x10^-6 m2/s flows through a 250mm diameter pipeline of the same relative roughness.
