Heavy fuel oil flows in a horizontal pipe with diameter of 95 cm. the oil flow rate is 0.4 m^3/s. the properties of heavy fuel oil are: density= 991 kg/m3 , and kinematic viscosity= 3.6x10^−4 m^2/s. (a) calculate the entrance length of this pipe. (b) obtain the pressure drop per unit length of the pipe and the centerline velocity. (c) obtain the shear stress at the wall and at a distance 20 cm from the centerline. (d) find the equation for the velocity distribution as a function of r only. (e) what angle is needed for a downhill flow in the pipe to make the pressure drop zero? is this possible? explain.
