An underwater gate 8 m wide is held closed by a force, F, as shown in the figure. If the force is applied at the middle of the gate, what is the minimum value required to keep the gate closed? take density of water= 996kg/m3

A semicircular, hinged gate separates two fluids on either side of a partition. Part (a) of the figure shows the geometry of the gate, and part (b) of the figure shows the whole system in side view. The radius of the gate (4 m) is equal to the height of the fluid on the right side of the gate (fluid 2), and the specific weight ratio of the fluids is γ2/γ1 = 1.5. At what height, h, will thegate just start to open?

Rectangle Gate AB has length L and width b into the paper is hinged at B and has negligible weight. The liquid level, water, h does not reach the top of the gate for an angle theta. Find an equation for the force P, required to keep the gate in equilibrium. Solve for width, b. In the figure. (hint: draw a free-body diagram for the left and right side of the gate separately)

An open manometer, shown in the figure, is installed to measure the pressure in a pipe carrying an oil (SG = 0.82). If the manometer liquid is carbon tetrachloride (SG = 1.60) determine the pressure in the pipe (in N/m2). Find the pressure head in meters of water column height.

The 2-m wide gate ab depicted on the right retains water 3 m deep. Determine the horizontal and vertical forces on the gate, then calculate magnitude and direction of the resultant force on the gate.

Problem: Use a unit length for the gate, determine the height h (m) in fluid 2 in the figure below if the weightless triangular hinged gate is in equilibrium in the position shown. Assume y₂ = 1.5 ₁ Triangular Gate 1m Fluid 1 45° Hinge Fluid 2

Please answer with a good explantion so I can understand the problem

Consider the pressure and force acting on the pool retaining a reservoir of water. Suppose the pool is 50m wide and the water is 8m deep, as illustrated below.   (a) What is the Gauge pressure on the dam due to the water?   (b) What is the absolute pressure at10m depth of the dam?   (C) Calculate the force exerted against the dam. Density of water is 1000kg/m3.

A vat contains a mixture of oil and water. The water forms a lower layer which is 0.8 m deep, and above it there is an oil layer 0.3 m thick. The density of water is 1000 kg/m³, and the density of oil is 800 kg/m³. Find the force on a flat door at the bottom of the vessel that has a cross-sectional area of 0.5 m². The acceleration due to gravity is 9.81 m/s². Oil, P. = 800 kg/m³ h, = 0.3 m %D Water, pw= 1000 kg/m3 h, = 0.8 m A = 0.5 m² O a. 5.1 kN O b. 5.4 kN Ос. 1.28 kN O d. 4.32 kN е. 10.2 kN

An underwater pipeline must be laid 40 meters deep. The density of sea water is 1 025 kg/m³. The pipe has a mass of 40 kg per meter and an outside diameter of 300 mm. The pipe must be anchored every 5 m to the bottom of the sea. (a) What will the vertical force be on each anchor if the 4.3 pipe is empty. (b) What external pressure must the pipe be able to withstand if it is not to be crushed. [1 592 N, 402,2 kPa]
