Fluid Flow Rate

Introduction: Today in many industrial processes, it is important to measure fluid flow rate within a system as a whole or in part accurately. This applies equally to both liquid and gasses equally (e.g. carbon dioxide, nitrogen, liquors and etc.) which are an integral part of the process, or to compress air, water or steam which are a fundamental to plant operation. The installation of any flow meter can be explained in two ways. Firstly, the process control where the flowmeter is used to measure the rate of fluid or energy flow to allow the process to be controlled and so to be certain that the end product is of the required quality. Second is the cost allocation where energy is used to provide process or space heating, it is fundamental to know where the costs associated with energy are actually being incurred. The cost of energy are allocated to a particular product, department or other user by flowmetering which usually result in a significant reduction in total energy costs. The advantage of measuring flow is that it can allocate heating costs. Not only that, it also improve process control, identify major energy users, monitor the results of process changes, check on steam boiler efficiency, identifying energy patterns through the day and provide management information. In the world today, orifice plates are still the most used type of flowmeter. The main reason why they are used over the other flowmeters is due to the fact that they offer cost benefits, especially in larger line size, and have proved to be rugged, reliable and effective over many years. Orifice plate continues to provide a very competitive solution where a need exists for a rugged, cost effective flow meter which has a turndown of not more than 4:1... ... middle of paper ... ...erefore a result can be very precise but inaccurate. So, experiment which has an accurate answer is said to be more successful experiment rather then an experiment which has precise value but inaccurate answer. Conclusion: To sum up, this experiment have proven that there will always be loss in the system but the system can be made more efficient to minimize the loss and therefore reducing the cost. The experiment carried out to determine the volume flow rate of experimentally and theoretically showed that there are some errors in the experiment when the experimental value was compared with the theoretical value. One of the most obvious possibility of an error that may have occurred during the experiment was the human error. However, these errors can be reduced by repeating the experiment for more than two times and also if possible by using better equipment’s.
