Discussion of Experiment

A centrifugal pump contains an impeller or set of vanes encased in housing. Energy is added to the fluid in the form of velocity and pressure as a result of the impeller turning. An engineer must determine the range of flow rates required when using a centrifugal pump. The centrifugal pump chosen for an application must have a head versus flow rate relationship matches the demand of the piping system connected to. Head and flow rate data can be presented in graphical or table form.

Discussion and Conclusion

The result of conducting this experiment for characterizing the head and flow rate relation is summarized in Table 1, Figure 1 and Figure 2. Table 1 – Centrifugal Pump @ 1750 RPM, shows the pressure, flow rate, and speed of the centrifugal pump for 8 settings. Also shown in table 1 are the uncertainties, corrected pressure calculation results, corrected flow rate calculation results, head pressure from calculations and ideal power of the centrifugal pump from calculations.

Figure 1 – Head Pressure versus Flowrate, shows the relationship of corrected flow rate (in GPM) with respect to head pressure (in PSI). The plot showing the relation is decreasing in flow rate as the head pressure increases. This shows that as the head of the centrifugal pump restricts the flow rate when closed or partly closed.

Figure 2 – Ideal Power versus Head Pressure (H), shows the relationship of corrected flow rate (in GPM) with respect to ideal power (in watts). The relationship shows that as the flowrate decrease the ideal power increases. When compared to the results of figure 1, the results show that as head pressure increases, the ideal power of the fluid also

    Centrifuge is a device in which solid or liquid particles of different densities are separated by rotating them in a tube in a horizontal circle. The dense particles tend to move along the length of the tube to a greater radius of rotation, displacing the lighter particles to the other end. English military engineer Benjamin Robins (1707-1751) invented a whirling arm apparatus to determine drag. In 1864, Antonin Prandl invented the first dairy centrifuge in order to separate cream from milk. And in 1879, Gustaf de Laval demonstrated the first continuous centrifugal separator, making its commercial application feasible. Using high pressure steam in a turbine that had oil-fed bearings meant…

    The main objective of this experiment is to verify the Bernoulli Equation using a Venturi meter which is a converging-diverging tube of known geometry which is attached to a pipeline to help measure different quantities of flow rates. Furthermore, different forms of Bernoulli’s Equation is used to calculate pressure head, head loss and velocity loss. After finding out the data, the measured values of the static pressure head for each increasing flow rate is compared with the theoretical value, calculated by the Bernoulli’s equation. The head loss is also found by measuring the 8th manometer on the manometer panel whose difference each time will give the head loss. The difference between the measured and theoretical value of static head is then found out to be due to the frictional losses…

    Centrifugal force depends on three variables: mass, speed, and radius. The speed is expressed in revolutions per minute (rpm), and the centrifugal force generated is expressed in terms of relative centrifugal force (RCF) or gravities (g). The speed of the centrifuge is related to the RCF by the following equation: RCF  1.118  105  r  (rpm)2 where 1.118  105 is a constant, determined from the angular velocity, and r is the radius in centimeters, measured from the center of the centrifuge axis to the bottom of the test-tube shield.…

    The rate of centrifugation is specified by the angular velocity measured in revolutions per minute (RPM), or acceleration expressed as g. The conversion factor between RPM and g depends on the radius of the sample in the centrifuge rotor. The particles' settling velocity in centrifugation is a function of their size and shape, centrifugal acceleration, the volume fraction of solids present, the density difference between the particle and the liquid, and the viscosity.…

    When the machine fails or break down, the consequences can range from annoyance to financial distortion, personal injuries and possibly the loss of life. For this reason, the early detection, identification and correction of machine problems paramount to anyone involved in the maintenance of industrial machinery to ensure continuous, safe productive operation. The use of machinery vibration and the technology advances that have been developed over the years make it possible to not only detect when a machine is developing a problem but to identify the specific nature of the problem for scheduled correction. In addition, human perception of touch and feel is somewhat limited and there are many common problems such as bearing and gear failure that are generally put out of the range of human perception. Thus vibration analysis of rotating machine not only minimises the need for extensive expenses but make it possible to detect developing problems which are out of the range of human sense of touch and feel. We introduce the beginning of vibration analysis and develop a simple, logical and systematic approach that has been proven successful in pinpointing the vast majority of the most common machinery problem. We intend to do a project on “Vibration analysis of centrifugal pump at BPCL Kochi Refinery”. The vibration analysis we have done is a part of predictive maintenance on rotary equipments. This technique is mainly used for the improved performance of equipments. Using this we can predict the condition of internal parts of the equipment. We are mainly dealing with the vibration analysis of centrifugal pump, compressors and motors. It includes typical causes of vibration like misalignment of shaft, looseness, bearing faults, unbalance, oil failure etc. This project explains the vibration analysis on pumps and motors of BPCL Kochi Refinery, the methodology, readings, analysis and the performance of vibration analysers through case study. All cases and…
