Oil (Density = 860kg/m3, Dynamic viscosity = 0.002 Pa.s) flows through a pipe of 100mm diameter with a velocity of 0.01 m/s. Determine friction

a 12" diameter pipe carries oil with a velocity distribution of v = 9(r1^2 - r^2) determine the average velocity and the value of kinetic energy correction

1. SAE 10 oil at 20°C (p = 869 kg/m3, /z = 8.14 x 10"2 N-s/m2) flows in a 200-mm-diameter pipe. Findthe maximum velocity for which the flow will be laminar.  [Indicate the formula used in determining the friction factor. (Colebrook Equation, Haaland Equation, andor Swamee Jain Equation). If not given, Use properties of fluid based ontemperature available ontheinternet.E.g.
