Faculty of Science, Engineering and Technology QUESTION 3 a. (9 marks) Air flows vertically upward in a converging pipe as shown in the figure. A water manome ter is connected to a Pitot tube in the large pipe section, and a piezometer, 1.5m from the datum in the smaller section. The deflection of the water manometer is H=5em. Assume a temperature of 20°Cand atmospheric pressure in the large pipe, and assume the air is incompressible.What s the velocity in the small section (V2)? V- 1.5 m Air Datum Water b. (6 marks) Water stored in a pressurized tank as shown in the figure. The water is discharged ugh a g10cm pipe that is that there are no head losses. What is the flow rate of water leaving the tank? the surface of the water. temperature of 20°C. sume ThinkCentre Deskin ni Esc ET F3 F4 F5 F6 F7 FB F9 F10 F11 S -Bac 2 5 6 4 8 9 C W E R T Y Q O P Caps Lock A D
