An inclined pipe of 4-inch ID is used to transport a viscous oil from one open-top container A to another open-top container B. The specific gravity of the oil is 0.9 and the viscosity of the oil is 20 cp. The length of the pipe is 100 ft. Oil levels in these two containers are shallow and the inlet and outlet pressures across the tube can be assumed to be identical – both 1 atm. What is the angle needed to maintain a flow rate of oil of 1 cuft / second? The levels of oil in A and B do not change – oil is continually added to A at the rate of 1 cuft / second and is continuously removed from B at the same rate. A
