12. A container filled with water and there are two holes, as shown in figure below. What is the ratio of x1 to x2? 20 cm 100 am 50 cmB X1 X2 13. Given frictionless flow of water at 125.6 ft'/s in a long, horizontal, conical pipe of diameter 2ft at one end and 6ft at the other. The pressure head at the smaller end is 18ft of water. Find the velocities at two ends and the pressure head at the larger end.
