Heat exchanger - Essay Example In this experiment, the shell and tube exchanger that was used comprised of a number of tubes that were parallel in a cylindrical shell which had no significance until 15%. The experiment was conducted in environmental ambient temperature and distilled was added to make it successful since it does not contain impurities and has less probability to cause damage to the equipment. There was no significant change because the percentage error obtained for heat transfer coefficients for both concurrent and counter current is below 15%. In comparison to the counter current, the overall heat exchanger for concurrent flow is under control since there was a significant change for counter current has a significant change. Based on the estimated overall heat transfer, the expected exit temperature has the percentage error for both co-current and counter current was below 15% and thus no significant change. During the experiment, the heat losses for both co-current and counter current were above the expected percentage value, therefore creating a mean of high heat losses. The percentage error of the overall heat transfer coefficient for the co-current and counter current were not as expected indicating a significant change in the co-current. This shows that the efficiency of the heat exchanger effects on parallel flow more than counter flow. Heat transfer is a widely used method of cooling warm fluids to lower temperatures while using a barrier to separate the two flows and is majorly applied in petroleum and chemical engineering. The shell and the tube heat exchanger are the equipment commonly used in this experiment because of the users’ ability to manage the pressures and temperature. In the shell and tube exchanger, the cylindrical shell is lined with some tubes internally. Its operation underlies the principle of two fluids flowing, one inside the tube and the other externally. The flows can assume either parallel or cross counter
