An oil with a viscosity of 0.4 N.s/m2 and a density of 900 kg/m3 flows through a pipe with a diameter of 0.02 meters. a) If the pipe length is 10 meters, what is the pressure difference (P1 P2) required for the flow rate to be 2x10-5 m3/s in the horizontal pipe? should it be? b) How many degrees () in the pipe for the oil to flow from the pipe with a flow rate of 2x10-5 m3/s without
