An oil (density = 900 kg/m3, dynamic viscosity = 0.06 poise) is flowing through a pipe of diameter 200 mm at the rate of 60 litre/s. If head loss due to friction for a certain length of the pipe is 10 m of water, what will be the power required to maintain this flow? [assume, Acceleration due to gravity = 10 m/s2]
