1. Calculate the force required F to maintain a square closed gate of 0.25 m2. Consider...
Question 2 (15 points) As shown in Fig. 2, if Ywater 9810 N/m2 and the gate is 2 m wide (into the paper), what is the moment M (N-m, clockwise is positive) at O to hold the gate closed? (Neglect friction and the weight of the gate.). Assume that Pam is constant in the air surrounding the system. м 45 Gate 2 m wide 1.2 m Water P atm Patm 0.6 m 0.3 m SG 6.0 Fig. 2
The rigid gate, OAB, in Figure is hinged at O and rests against a rigid support at B. What is the minimum horizontal force, P, is required to hold the gate closed if its width is 4 m? Neglect the weight of the gate and friction in the hinge The back of the gate is exposed to the atmosphere.
Question 4 (7 Marks) Tank ABCDE (Figure 4.1) contains an oil of SG-0.82. The tank has a width (normal to page) of 25m. The tank has a plain gate CD that is hinged at C. It is required to: a) Determine the direction, magnitude (in ton) and inclineation of the resultant hydrostatic force on the circular surface DE; b) Determine the hydrostatic pressure force (direction, magnitude and point of action) on plain surface CD c) Determine the minimum force F...
QUESTION 3 Figure below indicated that a plug with cone shape used to plugged a hole of 45 cm radius at one side of a tank that containing X fluid (SG-0.8). The cone is 1.5 m height and I.I m bottom diameter. Depth of cone center point to the surface liquid is 10m. a) Draw the distribution of pressure onto the plug b) Determine the force acts onto the plug Cone 10 m QUESTION 4 Figure below shows a water...
Dam Wall (7 marks) Fig 6 6. A circular gate AB of diameter 4 m is designed to close the water flowing out from the sloping wall of a dam structure. The gate is hinged at A as in Fig 6. Calculate (a) the magnitude of hydrostatic force acting on the circular gate and (b) the position of hydrostatic force from the water surface. (6 marks) 7. Using the data in Fig 7, (a) find va if vb is 3...
all questions please Name- Date Chapter 6 Laboratory Exercises 1. Consider the Coriolis force in the Southern Hemisphere and its effect on wind direction Following arguments similar to those given in the text (and in Figure 6.25) for the Northerm Hemisphere., (a) explain why the deflection resulting from the Coriolis force in the Southern Hemisphere is to the left. (b) Draw an area of low pressure with a few closed isobars. Label the isobars with realistic values of sea-level pressure....
