A rectangular gate is located at the end of a rectangular way with 3-m-wide and 8-m-high which is connected to a huge open reservoir overflowing with water as shown in Figure. The door is hinged at its base and held closed by a straight force, F R , located at the center of the gate. The maximum value for F R is 4000 kN. (a) Determine the maximum water depth, h, (b) Determine the moment that would apply to the gate. 2. A double U-tube manometer is connected to a pipe as shown in Figure. Taking the dimensions and fluids as indicated; calculate the absolute pressure at point at A (centre of the pipe). Take Patm 101325 Pa and the ρHg as 13600 kg/m3 . 10

The fluid has a SG of 0.85, and the manometer column height is 55 cm, as shown in Figure. If the local atmospheric pressure is 96 kPa, determine the value of h1. Note: consider the pressure as absolute pressure. 4. An inverted U-tube manometer connects pipes A and B as shown in Figure 3. The manometer fluid is oil of density 900 kg/m3 ; pipes A and B contain water. Calculate pressure difference between A and B where pA and pB are the pressures at the pipe centres, as shown.
