Water enters a cylindrical tank through two pipes at rates of 0.223 ft3/s and 0.557 ft3/s (see figure below – control volume is indicated by dotted lines). (a) Indicate if the flow is steady or unsteady. (b) Calculate the average velocity (in ft/s) of the flow leaving the tank through an 8-in inside diameter pipe if the level of the water in the tank remains constant.
