  • DESIGN AND BUILDING OF A SMALL SHELL AND TUBE HEAT EXCHANGER USING ALGORITHM

    ABSTRACT

    This research work is on Design and building of a small shell and tube heat exchanger using algorithm. A heat exchanger is a device which is used to transfer thermal energy between two or more fluid. This project is mainly focusing on designing one type of a heat exchanger which is shell and tube heat exchanger. In this project a fixed tube plate type shell and tube heat exchangers was chosen, exchanger of 150000 lb per hour of kerosene that will be heated from 75 to 120°F by cooling a gasoline stream from 160 to 120°F at a calculated heat load of 3240000. The specification of the Heat exchanger as well as the detailed mechanical design was calculated. It is established that the heat exchanger with gasoline at the shell side and kerosene at the tube side is adequate for the operation. The available area obtained from the calculation is 2105ft2 and also the overall heat transfer coefficient obtained is  Btu h -1 ft -2 °F-1  with a LMTD of  42.75°F. It is also seen that the heat exchanger is satisfactory and consist of 6 tube passes with tube outside diameter of 14 (BWG) and length of 24mm,the  shell outside diameter of 803.4mm and thickness of 3.72mm. The material for construction for the shell side is carbon steel.

  • PHYTOCHEMICAL AND ANTIMICROBIAL STUDIES OF THE METHANOL EXTRACT OF THE ROOT OF NAPOLEONAEA HEUDELOTTI (A.JUSS)

    ABSTRACT

    This project is on Phytochemical and antimicrobial studies of the methanol extract of the root of Napoleonaea Heudelotti (A.Juss). The extracts of the root part of Napoleonaea heudelotii were subjected to phytochemical and anti-microbial studies. Extraction was done by continuous Soxhlet extraction using methanol. The phytochemical screening of the crude methanol extract, chloroform and ethyl acetate fractions revealed the presence of carbohydrate, cardiac glycosides, saponins, steroids, triterpenes, flavanoids and tannins. The result of the antimicrobial screening of the crude methanol extract, ethyl acetate and chloroform fractions showed activity against Staphylococcus aureus, Streptococcus pyogenes, Bacillus subtilis, Escherichia coli, Salmonella typhi, Pseudomonas aeruginosa, Proteus vulgaris, and Candida albicans. However, the chloroform fraction was the most active fraction against the test microoganisms. The zone of inhibition of the methanol extract ranged between 16 mm and 21 mm, the chloroform fraction ranged between 17 mm and 25 mm while the ethyl acetate fraction ranged between 15 mm and 21 mm. The MIC results of methanol extract, ranged between 12.5 mg/ml and 1.562 mg/ml, chloroform fraction ranged between 12.5 mg/ml and 1.562 mg/ml, while ethyl acetate ranged between 6.25 mg/ml and 1.625 mg/ml. The MBC of methanol extract and chloroform fraction ranged between 12.5 mg/ml and 1.562 mg/ml, while that of ethyl acetate fraction ranged between 6.2 mg/ml and 1.562 mg/ml. The chloroform fraction being the most active fraction was subjected to extensive chromatographic purification; white crystalline solid labelled NHPE were isolated. The structures of the isolated compounds were determined to be a mixture ?-amyrin and ?-amyrin using 1D and 2D NMR.

  • ASSESSMENT OF PRODUCTIVE SKILL COMPETENCY LEVELS BASED ON GENDER AMONG SENIOR SECONDARY SCHOOL CHEMISTRY STUDENTS FOR ENTREPRENEURSHIP

    ABSTRACT.

    This project is on Assessment of productive skill competency levels based on gender among senior secondary school chemistry students for entrepreneurship. The study was an assessment of productive skill competency levels of secondary school chemistry students for entrepreneurship. Ten research questions and ten null hypotheses guided the study. A descriptive survey design was employed for the study. From the population of 6121 chemistry students, 1132 was sampled by balloting and used in the study.

    The study was carried out in all the secondary schools in the six education zones in Anambra state. Instrument for data collection was

    Test of Acquisition of science process skills (TASPS).  Mean scores were used  in answering the ten research questions, while the ten hypotheses were tested using t-test. From the analysis, the researcher found that: SS3 chemistry students possessed science process skills. There was no significant difference between the level of competence of the male and female SS3 chemistry students. The study has shown that at the end of three years of senior secondary school, the chemistry students possessed science process skills which if properly channeled will enhance their entrepreneurial abilities. Based on the findings and discussions, some recommendations were made: the State Ministry of Education should encourage exhibition of students’ products from time to time as this will encourage both teachers and students to improve  their productive skills. The examination bodies WAEC and NECO should encourage the productive skills of the students by emphasizing on questions that will require them to produce articles like soap, cream, salt, charging of battery etc so as to give those avenues to apply the Science Process Skills  (SPS) learnt in other practical aspects. Limitations of the study were stated and suggestions for further study proffered.
