Experiment 2 - Cooling Tower Demonstrator
OBJECTIVES
To determine the finale state properties of distribute and urine from tables or charts.
To determine efficiency and mass balances using steady flow equation on selected system.
To investigate the effect of cool down load on squiffy Bulb Approach.
To investigate the effect of circularise amphetamine on: (a) Wet Bulb Approach, (b) pressure drop by the packing.
INTRODUCTION
A cooling tower is a instigate rejection device, which extracts run off heat from processes to the atmosphere via a urine stream. The type of heat rejection in cooling tower is by evaporation of blue amount water from the water stream that flow through the packing inside the cooling tower. The waste heat send to water stream and evaporate small portion of water in the stream to the air and increase the temperature of the air and its proportional humidity, and this is discharged to atmosphere. Cooling towers uses either the process of evaporation of water to remove the heat and cool the fluid to the wet-bulb air temperature, or uses only air to cool down the fluid to the dry-bulb air temperature.
When air is used to cool down the water, radiation effect, conductivity and convection effect, and alike evaporation effect would occur. The saturation pressure alike(p) with the surface temperature is the vapour pressure at the liquid surface. This evaporation process in an enclosed space shall continue until the air is saturated and its temperature equals to the surface. Results in this experiment are identified with the arrest of thermodynamic properties, and calculated by using the specific atomic number 1 and specific heat capacity, Daltons and Gibbs Law, the formula of humidity and saturation, and also the steady flow energy equation. Cooling towers, which are introduced as one of the direct contact heat exchangers and in several(prenominal) heat transfer applications, are usually used for cooling the circulating...If you want to get a full essay, order it on our website: Orderessay
