rates and both static andtotal pressure heads in a rigid convergent/divergent tube of known geometry for a range of steady flow rates. The Bernoulli’s theorem ( Bernoulli’s t heorem‚ 2011) relates the pressure‚velocity‚ and elevation in a moving fluid (liquid or gas)‚ the compressibility and viscosity(internal friction)of which are negligible and the flow of which is steady‚ or laminar. In order to demonstrate the Bernoulli’s theorem ‚ the F1-15 Bernoulli’s Apparatus Test Equipment isused in

A Short Essay on Freedom What exactly is freedom? Can you taste it‚ see it‚ reach out and touch it? The answer to these questions is no. However‚ if reflected upon‚ freedom can certainly be felt‚ not by the hands but by the emotion called feeling. Since all we can do is describe properties of freedom‚ the question remains how freedom is explainable with words. Youth are not burdened by restrictions placed upon adults; therefore‚ a simpler idea of being able to

Anatomy and physiology of the brain and spinal cord The brain is a spongy organ made up of nerve and supportive tissues. It is located in the head and is protected by a bony covering called the skull. The base‚ or lower part‚ of the brain is connected to the spinal cord. Together‚ the brain and spinal cord are known as the central nervous system (CNS). The spinal cord contains nerves that send information to and from the brain. The CNS works with the peripheral nervous system (PNS). The PNS
