Q2. A cylindricai tank of diameter 2.5 m is founded with its axis horizontal. The tank contains water in the bottom half and an oil of relative density 0.82 on the top half with a common interface. The fluids are under pressure and a pressure gauge on the top of the cylinder reads 15 KPa. Calculate the force per meter length on the upper half of the cylindrical tank.

a) Water discharges at a rate of 5L/s through a nozzle. The jet, 25 mm in diameter, strikes a flat plate held perpendicular to its line of flow. Determine the magnitude of the force on the plate.

The tank shown has one curved surface restraining a body of static fluid with 3.55 kPa air pressure above the fluid and sg = 0.88, with the following dimensions: w = 5.50 m h1 = 2.1 m D1 = 0.85 m Required Compute the magnitude of the resultant force, in kN, to the nearest 100th. Fluid sg = given hl D1

A suspended gate that’s able to pivot from the top seperates two liquids. There is a stopper that prevents the gate opening anti-clockwise. The gate has a height of 0.5m. The liquid on the right is three times as dense as the liquid on the left. The liquid on the left has a depth of 0.3m. 1) What is the minimum depth of liquid on the right for the gate to open. 2) Comment on the ability to solve this question if the liquid on the left was 0.5m (filled to the top)
