tubes in which fluids enter. It consists of two streams one for hot water and the other for cold water. The heat exchanger also consists of a control valve which is used to regulate the volume and mass. It also consists of cooling water couplings which are used to switch the cooling water direction from counter current to concurrent and vice versa. Introduction A heat exchanger is used in many different applications in a wide range of fields. The importance of a heat exchanger is to transfer fluid

the test pieces and then testing the hardness of the particular steel from the quenched end‚ to the end of the test piece. Taking these different points will enable me to find out how the hardness varies throughout the test piece considering the cooling rate of the metal and thus illustrate the hardenability of the steel. I will also analyse how adding different alloying elements to the steel can improve its hardenability. Theoretically what should happen is that as the distance increases from the

properties of commercially pure aluminium. The investigation was consisted of identification of commercial aluminium through colour identification in chemical test and its subsequent heat treatment. The experimental parameters were heating temperature‚ cooling rate and quenching medium. The prepared specimen were heated at 300‚ 500 and 600 °C and then subsequently cooled either in open air‚ slowly in the furnace or quenched in furnace oil. Hardness of the heat treated and without heat treated specimen

are believed to have a cooling effect. Natural factors also contribute. According to the historical temperature record of the last century‚ the Earth ’s near-surface air temperature has raised around 1.3 ± 0.32 ° Fahrenheit (Wikipedia‚ 2012). Although human induced global warming is a popular theory‚ it is misleading because climate change has occurred throughout history‚ our most recent period of warming ended over ten years ago‚ and the earth is currently in a state of cooling.

the strength of the evidence to support treatment with mild/moderate hypothermia. Evidence is strongest for prehospital cardiac arrest and neonatal hypoxic-ischemic encephalopathy. For traumatic brain injury‚ a recent meta-analysis suggests that cooling may increase the likelihood of a good outcome‚ but does not change mortality rates. For many of the other indications‚ such as stroke and spinal cord injury‚ trials are ongoing‚ but the data is insufficient to recommend routine use of hypothermia

Before the cooling procedure can begin the patient is given a sedative and a neuromuscular blocker to prevent shivering. There are multiple external techniques such as cooling blankets‚ ice packs‚ wet towels‚ and a cooling helmet; however all of these are slow to cool core temperature (University of Chicago‚ 2008). An intravascular heat exchange device has recently become available; this machine enables rapid cooling and precise temperature control (University of
