A concrete tank structure is constructed below ground level for a large commercial swimming pool in an area where dense granular soil exists (20 kN/m3 wet unit weight). The diving board end of the tank-pool is 6 m deep (below the ground surface). For the design, it is assumed that the groundwater table could rise close to the ground surface at various times. For the condition where the pool is empty, estimate the total lateral pressures (due to soil and to water) acting against the exterior side of the end wall at points 2 m, 4 m, and 6 m below the ground surface for the high water table condition. Assume the submerged unit weight for the soil is half the indicated unit weight (the given unit weight is a wet but not saturated unit weight).

Problem An open circular tank of 20 cm diameter and 100 cm long contains water upto a height of 60 cm. The tank is rotated about its vertical axis at 300 r.p.m., find the depth of parabola formed at the free surface of water.

Failure of Concrete in Multiaxial Stressesmal m Background A concrete gravity platform is one that is placed on the seabed by its own weight, and is capable of withstanding the environmental forces (wind and waves) it may be exposed to during its lifetime. These gravity-type concrete platforms are used for oil-drilling purposes in the oil industry. They are used when the soil/rock of the seabed is hard and relevant for supporting them since they rest directly on the ocean floor without pile foundation. Concrete platforms are larger and heavier than steel platforms. Although there are various designs of a concrete gravity platform, the base part is usually made of reinforced concrete and consisted of huge sub-sea concrete tanks. These tanks are used for the storage of crude oil, at the same time provide the stability of the overall structure. We would like to consider one of the concrete cylinders (see Figure 1) as part of the base of a gravity platform. The base structure is built to…

13. An open tank contains liquid 8 m deep of unit weight of 9 kN/m3, water of unit weight of 9.81 kN/m3 is poured over the liquid and the the total depth of both liquids is 5 m. Obtain the gage pressure in KPa in the interface of the two liquids

The diameter of a pipe gradually reduces from 1 m to 0.7 m. the pressure intensity at the centre line of 1 m section is 7.848 kN/m? and rate of flow of water though the pipe is 600 liters/s. The intensity of pressure (N/cm?) at the centre-line of 0.7 m section is (Correct up to 2 decimals)

Correct answer please

A water pie gradually changes from 150mm ata point x to 450mm at point y. Point x is 5m below point y. Evaluate the pressure difference between x and y when the flow is 180L/s. Neglect losses.

2 - Water is in a horizontal tube of length 250 m and diameter of 15 cm at a speed of 1.2 m/s. Note that the density of water is 1000 kg/m³ and a viscosity of 0.01 N.s/ m. Find the pressure difference along the length of the pipe? Note that the roughness modulus is 0.000045

I need the answer as soon as possible

The diameter of a pipe gradually reduces from 1 m to 0.7 m. the pressure intensity at the centre line of 1 m section is 7.848 kN/m2 and rate of flow of water though the pipe is 600 liters/s. The intensity of pressure (N/cm2) at the centre-line of 0.7 m section is
