company provided the author with the majority of the information contained in this project. To get an understanding and appreciation of the value of refrigeration and how it works‚ the history and mechanical engineering theory of refrigeration will be briefly explained at the beginning. 2.0 The History of Refrigeration. Before 1938 refrigeration did not really exist. Wet ice and salt were used to preserve poultry‚ dairy products and meat. People used “larders” in their houses to keep the meat

Lab report As part of my module Nip1002 I was required to perform a set of observational skills which included; pulse‚ blood pressure‚ respirations‚ hand washing and urinalysis and then compare them to previous results. In this lab report I am going to discuss blood pressure in detail. Procedure * Explain the procedure to the patient and gain consent * Wash hands thoroughly following the hand wash technique to prevent the transfer of bacteria * Clean equipment e.g. blood pressure cuff

Introduction Electric fields are produced by charges. Charges may be one of two signs‚ positive or negative. Changing the positions of positive and negative charges can alter an electric field. An electric field is a vector quantity from which the magnitude and direction of an electric force is determined. The electric force is due to the presence of charged particles. Charge is the attribute of matter by which matter responds to electromagnetic forces. Charge is responsible for all electrical

Air Conditioner Report The use of concrete blocks in buildings construction decreased natural ventilations in the structures. The situation was worsened by house designs in urban areas where there were small spaces left for air waves. This lack of ventilation and variations n weather patterns necessitated a gadget that would keep rooms at suitable temperatures for human comfort. The air conditioner has a mechanism that absorbs humidity from the air to create a cooling effect inside buildings when

5. Experimental Setup of the SRM Drive using Matlab Simulink The experimental setup is shown in Figures 5 and 6. Shows the GA-PID and ACO-PID controllers for a 3-phase 60KW SRM motor which are implemented & simulated by using Matlab-Simulink software program. Motor parameters used for simulation are given in Table 1. Tables 2 and 3 shows the GA-PID and ACO-PID controller’s parameters. the response of Kp‚ Ki and Kd parameters are summarized on table 4 which shows that the proportional controller

INTRODUCTION The measurement of fluid flow is very important in our daily life from measurements of blood-flow rates in human artery to the measurement of liquid oxygen in a rocket. In this experiment‚ students are to adapt to various ways to measure the flow of essentially incompressible fluids by using the flow measuring apparatus. Students will also be able to understand the application of Bernoulli’s equation in this experiment. The flow is measured by using a venture meter‚ an orifice meter
