A rectangular vessel when full of water

The damping efficiency of vertical porous baffles is investigated for a dynamically coupled fluid-vessel system. The system comprises of a two-dimensional vessel, with a rectangular cross-section, partially filled with fluid, undergoing rectilinear motions with porous baffles obstructing the fluid motion. The fluid is assumed to be inviscid, incompressible and irrotational such that the flow in each region is governed by a velocity potential. Numerical evaluations of the characteristic equation show that the lowest frequency mode typically has the smallest decay rate, and hence will persist longest in an experimental setup. The maximum decay rate of the lowest frequency mode occurs when the baffles split the vessel into identically sized regions. Choudhary, S. When a vessel, partially filled with fluid, is constrained to move in some prescribed motion, the fluid within can experience complex motions. As the fluid sloshes back and forth in the vessel it interacts with the vessel walls, generating forces and moments on the vessel. If the vessel is free to move under the forces generated by the fluid motion perhaps in some constrained manner then this coupled motion could be stabilizing or destabilizing to the overall system. A simple everyday example of this instability is when we spill coffee while walking to our seat [ 1 ]. The destabilizing aspect of coupled sloshing can have disastrous effects, such as capsizing King crab boats [ 2 ], so being able to identify and mitigate against such effects is important. In the current paper we consider a simple model which mitigates against destabilization via the use of porous baffles. Rigid impermeable baffles were first used to minimise sloshing in fuel tanks within the space industry [ 4 , 5 ], mainly by simply blocking the fluid flow.

It is known that it takes five minutes to empty a rectangular vessel when filled one-third of its volume with kerosene through an orifice in its bottom. A hemispherical tank full of water is emptied by a pipe at the rate of 25 7 litres per second. How much time will it take to empty half the tank, if it is 3m in diameter? A cylindrical tank full of water is emptied by a pipe at the rate of litres per minute. How much time will it take to empty half the tank, if the diameter of its base is 3 m and its height is 3. A hemispherical tank of radius 1. It is connected with a pipe which empties it at the rate of 7 litres per second. How much time will it take to empty the tank completely?
