Pressure Vessels

The term pressure vessel refers to a closed container that contains gas or liquid at a different pressure than environment pressure. The pressure vessels have a wide scale of applications in our day-to-day lives and other industrial places. Some common examples of pressure vessels are gas cylinders, autoclaves, compressor vessels, etc.

Some types of bacteria containchains of ferromagnetic particles parallel to their long axis. The chainsact like small bar magnets that align these magnetotactic bacteria withthe earth’s magnetic field. In one experiment to study the response ofsuch bacteria to magnetic fields, a solenoid is constructed with copperwire 1.0 mm in diameter, evenly wound in a single layer to form a helicalcoil of length 40 cm and diameter 12 cm. The wire has a very thinlayer of insulation, and the coil is wound so that adjacent turns are justtouching. The solenoid, which generates a magnetic field, is in an enclosurethat shields it from other magnetic fields. A sample of magnetotacticbacteria is placed inside the solenoid. The torque on an individualbacterium in the solenoid’s magnetic field is proportional to the magnitudeof the magnetic field and to the sine of the angle between the longaxis of the bacterium and the magnetic-field direction What current is needed in the wire so that the magnetic field…
