Question 2 (15 marks) 1 CLO1 CLO Marks a) A rectangular gate AB in the Figure...
A channel is closed by a rectangular gate shown in the Figure below. The gate which is hinged at the red circle in the figure is 7 m high and 1 m wide. It has seawater to the left to a depth of 7 m above the baseline and on the right has freshwater to a depth of 9.5 m above the baseline. The density of seawater is 1025 kg/m2, and density of freshwater is 1000 kg/m. Calculate the positive...
Gate AB in Figure A2 is a homogeneous mass of 180 kg, 1.2 m wide into the paper, hinged at A, and resting on a smooth bottom at B. All fluids are at 200 C. a) If the moment about the centre of gravity of a submerged plate at an angle e is defined as FYCP = Then show that this moment is given by [5marks] [3 marks b) Draw a diagram with all forces acting on the gate AB...
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 TWO (15 marks) A. A small chemical-industry tank fitted with a manometer as shown contains a dense fluid with specific gravity S 3.0 and 20 cm deep. Workers should have added water to a depth of 15 cm above the dense fluid. What height Ah do you expect to find when you inspect the tank? (7 marks) 15 cm Water Ah? 20 cm S 3.0 B. A sea-water aquarium is planned to have a circular window with diameter D-80...
QUESTION 2A (11 marks) [Allow 13 minutes] Water flows over a stationary, smooth, flat rectangular plate with dimensions 0.4 x 0.25m as shown in the figure below. The plate has its long axis parallel to the direction of flow 0.4 m U1 m/s 0.25 m Answer the questions below where the properties of the water are (p 1000 kg/m, v 106 m2/s): a) Determine the nature of the boundary layer over the plate if the approach velocity of the water,...
