GENERAL INSTRUCTIONS TO STUDENTS

FLUID MECHANICS AND MACHINERY LABORATORY

The purpose of this laboratory is to reinforce and enhance your understandingof the fundamentals of Fluid mechanics and Hydraulic machines.The experiments here are designed to demonstrate the applications of thebasic fluid mechanics principles and to provide a more intuitive and physicalunderstanding of the theory. The main objective is to introduce a variety of classical experimental and diagnostic techniques, and the principles behind these techniques. This laboratory exercise also provides practice in making engineering judgments, estimates and assessing the reliability of your measurements, skills which are very important in all engineeringdisciplines.Read the lab manual and any background material needed before youcome to the lab. You must be prepared for your experiments before comingto the lab. In many cases you may have to go back to your fluid mechanicstextbooks to review the principles dealt with in the experiment.Please actively participate in class and don’t hesitate to ask questions.Please utilize the teaching assistants fully. To encourage you to be prepared and to read the lab manual before coming to the laboratory, unannouncedquestions may be asked at any time during the lab.Never carry out unauthorized experiments. Come to the laboratory prepared.If you are unsure about what to do, please ask the instructor.Carelessness in personal conduct or in handling equipment may result in serious injury to the individual or the equipment. Do not run near movingmachinery. Always be on the alert for strange sounds. Guard againstentangling clothes in moving parts of machinery.Students must follow the proper dress code inside the laboratory. To protectclothing from dirt, wear a lab coat. Long hair should be tied back.Shoes covering the whole foot will have to be worn.Don’t forget to bring calculator, graph sheets and drawing accessories whenyou come to lab. In performing the experiments, please proceed carefully to minimize anywater spills, especially on the electric circuits and wire. Make your workplace clean before leaving the laboratory. Maintain silence, order and discipline inside the lab. Don’t use cell phones inside the laboratory. Any injury no matter how small, must be reported to the instructor immediately.Start writing your Laboratory records early, don’t wait till the day before the lab records are due. Most experiments require a significant amount of analysis, which cannot be done properly if you start one or two days before the due date. Start early and give yourself time to get help in case you run into problems, we can not help you if you wait till the last moment.Wish you a nice experience in this lab!
