How to synthesize nanomagnetic fluid

Using agate mortar, crush Chloride crystals of two metals, say cobalt chloride and iron chloride into fine powder. Put the fine crystals in a beaker and add distilled water so that we obtain a concentrated solution. Using high energy ball milling apparatus, ball mill it for 2 hours in a 650 rotations per minute speed. Add potassium hydroxide solution until it become brown. If it is not becoming brown, add a few drops of concentrated sodium hydroxide. The solution is subjected to heating till it boils. Let it remain there for 2 minutes. Ball milling shall repeated to 3 hours in a 600 rpm speed now. Filter the liquid and residue be dried using oven. Dried samples are heated to 773 K using a quality furnace. Put water, oleic acid and paraffin liquid in equal amount and ball mill it for 10 hours in a relatively low rpm (250 rpm enough). The resultant fluid is nanomagnetic and very much useful.

Compounding (Staging) of Impulse Turbine

In an impulse turbine, the steam expands completely in one stage (i.e., the entire pressure drop from high pressure to low pressure takes place in only one set of nozzles). As a result, the rotor rotates at a very high speed of about 30,000 rpm (K.E. is fully absorbed). This high speed poses number of technical difficulties like destruction of machine by the large centrifugal forces developed, increase in vibrations, quick overheating of bearings, impossibility of direct coupling to other machines, etc. To reduce the speed, reduction gearing is not preferable because of large and bulky construction. Hence a method of reducing the speed of the turbine is adopted. To overcome the above difficulties, the expansion of steam is performed in several stages. A number of successive stages are usually arranged one behind the other such that the expansion of steam would perform in several stages. Utilization of the high pressure energy of the steam by expanding it in successive stages is called Compounding (Staging).

Simple Impulse Turbine (De-Laval Turbine)

The above figure shows a simple single stage Impulse turbine. It consists of a wheel which is fitted upon turbine shaft. There is only one set of impulse type blades, which are rigidly fixed around the wheel. The steam enters through one set of convergent-divergent nozzle, fitted with the casing at high (inlet) pressure PH and low (inlet) velocity VL. The steam expands in the nozzle and impinges on the blades. As a result, pressure drops to PL with increase in velocity and the wheel rotates. As the steam passes over the blades, the pressure PL remains constant with decrease of velocity. But at exit (VL), it will be still higher than at its entry as shown in the figure below. Hence, there will be considerable loss in kinetic energy.

Opensolaris 2009.06

A new operating system was released by sun Microsystems recently with latest tools. They named the operating system as opensolaris 2009.06. The operating system promises significant improvement in networking, storage and virtualization. This operating system included project crossbow into it, which features complete rearchitecture of the network stack. Networking performance for virtualization in combination with processors connected to fast networking interfaces is highly appreciable here. Optimization of storage systems by flash devices is possible without the support of small caches on RAID controllers.
