Question 1. Water is stored either side of a vertical lock gate as shown in Figure Q1 The water level on one side of the wall is 10.0 m, on the other side it is 4.0 m. Determine the net force on the wall, per metre length, and the location of the point of action of the force. 10.0 4.0 FIGURE Q1
Question 2. A differential U-tube manometer is to be used to measure the difference between 2 points on a horizontal water pipeline as shown in Figure Q2. If the difference in level on the manometer h is 176 mm, and the relative density of mercury is 13.6, show that h g p p wm w ?? ? ?? ? ? ? ? 1 2 1 ?? ? and determine the difference in pressures p1 – p2.

Question 3. Find the head, h, on the mercury manometer.
Question 4. A vertical gate is located at the side of a tank containing water, as shown in Figure Q4. The top of the gate is 2 m from the top of the water level in the tank. Calculate the magnitude and location of the resultant force on the gate if the gate is a) Rectangular with a width of 2 m b) Circular c) Triangular with the apex at the bottom and a top width of 4 m Figure Q4 Note: Please submit the report of coursework (with coversheet) at Faculty office by Friday (4 pm), 10 May 2012 All coursework should be written using a word processor and graphical software.
