This study is conducted because of the need to know whether it is feasible to upgrade the system from level 2 to level 3. The study is limited only to the technical feasibility. Financial and economic viability were not considered. The present demand is projected to fifteen (15) years and the supply is evaluated whether it can cater the demand. The existing facilities are also examined whether it can be utilized for upgrading the system. Hydraulic principles and formulas are used in the design and computations of the data.

This manual was originally intended as a supplement to the very excellent textbook, "Power Plant Engineering" by F.T. Morse. But recognizing the needs for the presentation of the principles and the formulas involved in such solutions, the undersigned decided to include both theories and solutions to problems, but no attempt to changes has been made to the presentation, because that would implicate the standard textbook by F.T. Morse. The primary aim of this manual is to provide the student in acquiring a more thorough and comprehensive knowledge in this basic field as well as invaluable assistance from time he studies on the subject in Power Plant as undergraduates. The student is strongly advised to read the discussion of the subject matter at the beginning of each chapter. In them, he will find several hints, and classification of several basic principles so important to an effective teaching. By presenting here several solved problems from other textbooks, since the problem solved here, have been presented in much detailed forms. Likewise, the users are advised to pay careful attention to the explanation and notes.

Jr. Refrigeration industry began as soon as man began to preserve his food. It grew up with civilization as man's needs for preservation increased. A practical problem arose out in the newly inducted City of Sagay (formerly municipality of Sagay) that there is a need for an ice-making plant to supply the increasing demand of the different sectors in the city. During the recent survey, it was shown that there was a lack of ice supply with the three different sectors, namely: the agroindustrial sector, commercial sector and the household sector. The agro-industrial sector consists mainly of fishing industry. It is a regular consumer of ice which avails it in bulk or in greater volume. According to the Bureau of Fisheries, there are 2,033.82 hectares of bangus culture in this city which is having 1,283.4 metric tons per year production as of 1997 (see Table 1 of Chapter Three). By average, one ton of fish needs two tons of ice from harvest to delivery. However, producers use an average of 1.5 tons of ice per ton of fish for economic reasons. In offshore fishing an average of 3,247 metric tons is produced yearly for a motorized boat and about 675 metric tons is produced yearly for a non-motorized boat (see Table 2 of Chapter Three). In the commercial and household sector, ice consumption is increasing due to the fact that commercial establishments are also increasing in number. According to the surveys conducted, an average of 30 kg. of ice is used per day for these establishments, about 24 kg. of ice is consumed daily for ice cream vendors and about 20 kg. for the daily consumption of ice scramble vendors (see Table 3 of Chapter Three). Household sector is the least consumer of ice. Ice consumption in this sector is affected by seasonal factor such as the dry season, beginning December to May, demand for ice is high, peaking in the month of March and April. In the neighboring towns and municipalities of the city, people had been greatly affected by the economic situation particularly that of the fishing industry. People are deprived to invest their time and money, admitting imminent loss on their investment even though with the existing ice and cold storage plant in Bacolod City and Cadiz City. Because of the increase in demand, people are not contented with the presence of existing plant. There should be an additional establishment of ice and cold storage plant to overcome the tremendous growth in the fishing industry of the nearby towns. Now, if the fishing industry is to perform into a progressive one, there must be enough access to fish preservation to avoid increase of fish spoilage which causes the cut-down of the development of the fishing industry and the province as a whole. As a result, there must be an additional establishment of ice plant, as well as future expansion should be properly emphasized. This plant therefore is to help economic growth particularly in agro-industrial, commercial and household sectors in the city and around the area of the nearby towns. Statement of the problem It is the purpose of this study to establish an Ice-making Plant (50-ton capacity) in Sagay City for the year 1998 when the demands are taken as a whole and when grouped according to selected variables. More specifically, this study is aimed to accomplish the following problem objectives: A. Data for agro-industrial sector which constitutes a greater market consumers were mostly derived from the Bureau of Fisheries and Aquatic Resources in the province of Negros Occidental in the year 1997. B. Surveys and estimates were conducted at random but were seen to it that these present the majority of the people C. All other items that could not be estimated realistically were assumed to give optimum results.

Laboratory II Magay, Reynaldo B. This study was conducted because of the need to compile the test procedures contained in scattered materials (see references) into a single manual. It is also the object of this study to identify and list all equipment, materials, and apparatus for my institution (the State Polytechnic College of Palawan) to complete the set-up of its present M.E. Laboratory room. Prominent in the promulgation of such standard tests are the American Society of Mechanical Engineers (ASME), the Society of Automotive Engineers (SAE), the U.S. Bureau of Mines, and the manufacturers themselves. Intended for the B.S. Mechanical Engineering students of the State Polytechnic College of Palawan (SPCP), the test procedures contained in this proposed manual was adapted to the available options and present resources of the institution. Simplicity, economy, safety, and ease of test conduct were the criteria in the design of this manual. Included are the acceptance and test procedures for solid and liquid fuels, reciprocating engines, external-combustion systems (steam-generator), and centrifugal pumps. Introductory procedures were also added for the students to familiarize with engine basic measurements, operation, and design features before proceeding to performance testing proper. To achieve coincidence between theory and practice, the students are encouraged to analyze and identify the principles applied in an actual engine (design or operation) and compare them with the hypothetical engines of Thermodynamics.
