A cylindrical tank contains 1.0m of mercury (SG-13.6) and 3.0m of water. To look into the tank. a viewport measuring 0.60m by 0.60m was installed 0.60m above the base of the tank as shown in the figure. (a) using the pressure prism concept. determine the total force (in kN) acting on the view port due to water. (b) using the pressure prism concept. determine the total force (in kN) acting on the view port due to mercury. (c) What is the total force acting on the view port in KN? (The total force acting on the view point is equal to the sum of the component forces due water and mercury.)

The gate shown in the figure is hinged at A and rests on a smooth floor at B. The gate is a square in shape with 3m x 3m in dimension, while it is submerged in oil (SG = 0.82) as shown. The air above the oil surface is under a pressure of 7KPa. If the gate weighs 5 KN, determine the vertical force "T" required to open the gate. (Notes: Hydrostatic force "F" is always perpendicular to the plane surface. Also, the h ̅ is the pressure head located at the center of gravity of the object, which means, what will be the height of the oil if I am going to convert the pressure at the top into oil)

i attached the screenshot please help me to find the answer of the  wrong one

A square plate is submerged in water as shown below. Set up an integral to find thehydrostatic force against one side of the plate. (Use the fact that the weight density ofwater is 62.5 lb/ft3, and that pressure,P=δd) DO NOT EVALUATE THE INTEGRAL.

A 10000 litre water tank is placed on a building roof and filled to capacity.  The empty tank has a mass of 550kg.  It is supported on 4 feet, each of which is a 300 x 300 mm steel plate.  What is the pressure exerted by each plate, in Pa?  (Round your answer to 2 significant figures)

The total pressure force of a square plate is 25 kN, placed vertically in water so that the center of the plate is 1.5 m below the free surface. Determine the size of the plate and the depth of center of pressure. The above square plate is taken out of the water which weighs 370.5 N in air and 180.3 N in water of specific gravity 0.99. Find the volume and specific gravity of the square plate. Draw a neat sketch.

Consider a U-tube mercury manometer oriented vertically. One end is completely sealed with a total vacuum above the column of mercury. The other end is open to the atmosphere where the atmospheric pressure is that for standard sea level. What is the displacement height of the mercury in centimeters, and in which end is the mercury column the highest?The density of mercury is 1.36 × 104 kg/m3.

Please sir soolvee this questionnnn, thanks a lot siiirrr
