operated co-currently or counter currently. In the former‚ both fluids involved are fed into the unit from the same point causing them to flow along each other. In counter current operation‚ the liquid is fed at the top of the absorber‚ flows downwards and contacts with rising gas fed from beneath. Absorbers can be classified as tray towers or packed towers. In tray towers‚ the interfacial surface area required for contact between the two fluids is provided by stepwisely arranged plates or trays whereas

Abstract Meningitis is an infection of the subarachnoid space (located between the middle arachnid matter and the inner pia mater) of the meninges‚ which is the thin layer of tissues that line the brain and the spinal cord. Cerebrospinal fluid flows through the subarachnoid space and the meninges‚ providing cushion for the brain and the spinal cord‚ and filling the internal spaces within the brain. There are 2 main types of meningitis‚ including bacterial meningitis and viral meningitis

Machining Operations In MACHINING‚ the shape‚ size‚ finish and accuracy are obtained by removing the excess material from the workpiece surface. Various surfaces are obtained as an interaction between a workpiece and a cutting tool with the help of a contrivance known as MACHINE TOOL. Prof. S.K.

total drag of an object may be due to pressure as well as frictional effects. In this situation the coefficient of drag‚ CD‚ is defined as Equation 1 where F is the force‚ AP is the projected area of the surface‚ is the density of the fluid‚ and v∞ is the free-stream fluid velocity. The quantity is often called the dynamic pressure. This equation can be used to solve for the coefficient of drag from experimental data. The force and the air velocity can be measured during an experiment‚ the projected
