### Open Channel Flow LAB REPORT

Aim TO study the open channel flow in a rectangular channel Objectives 1. Investigate the uniform flow condition in open channel flow 2. Verify the manning’s equation Theory on Open Channel Flow  According to Dr. Khalil M. ALASTAL (n.d) an open channel is like a duck with flowing fluid and whose surface is exposed to atmosphere. As the atmospheric pressure remains constant through the length of duct so the fluid flows only due to the difference in potential energy. According to Ivan Gramatikov (n.d) flow rate of water in a channel is the product of its area with the velocity of water through that area  Q=A×V Where A is area of cross section and V is velocity of the fluid. Volumetric flow rate is the ratio of volume of flowing fluid to the time taken Q=∆V/t.  Area of the rectangular channel is the product of its width with the depth of the water flowing through that area A=b ×y_o.  Where b is the width of the rectangular channel and y_o is the depth of the flow. According to David Kni

### VENTURI METER AND ORIFICE PLATE LAB REPORT

Venturi meter effect and orifice plate effects are two main and very important phenomena in the fluid mechanics sub-field of mechanical engineering.  In this post, the effect of the venturi meter and orifice plate on the fluid flow will be discussed and complete work will be presented in the form of a report.  Aim This experiment aims to study the overall meter coefficient C of the  Venture meter and Orifice plate Objective The objectives of this experiment are 1. Understand the effect of a decrease in the area on the velocity and pressure of the flowing fluid 2. Understand the relationship between velocity and pressure of flowing fluid 3. Find the meter coefficient for the venture meter and orifice plate Venture Meter According to Michael Reader-Harris (n.d), a Venture meter is an instrument used to study the flow of fluid when it passes through the converging section.  There is an increase in the velocity and decrease in the pressure of the flowing fluid when the area av

### Analysis of three different material for flywheel

Current selection of material and manufacturing process for the flywheel has been clearly described and critically evaluated in Project 2 - Analysis of current material and manufacturing process of flywheel but there are other materials and manufacturing process that can be used instead of current material and manufacturing process to increase the performance, reliability and cost effectiveness of flywheel. Three of these materials and their manufacturing process are discussed below.

### Analysis of current material and manufacturing process of flywheel

Flywheel is a mechanical device used to store the rotational kinetic energy. The main application of the flywheel is to provide the kinetic energy whenever the load torque is greater the drive torque. Amount of energy store in a flywheel depends on three things geometry of flywheel, angular velocity of flywheel and density of material used.  Whereas the flywheel ability to handle the stresses and range of angular velocity at which it can rotate safely, depends on the material of the flywheel. Therefore the material selection is one of most important aspect of flywheel manufacturing.

### Fused Deposition Modeling - 3D Printing

Fused deposition modeling is an additive layer manufacturing process also known as layer by layer manufacturing process because in this process a 3 dimensional object is made by adding very thin 2 dimensional layers. Process starts with generating the computer aided design (CAD model) of the component which needed to be manufactured. Then second step is to convert the computer aided design file in to STL (standard triangulation language) file, this file format is internationally accepted by all additive layer manufacturing machines. Third step is to slice the 3 dimensional STL file into 2 D cross sections, this is done by the additive layer manufacturing machine. In fourth step the physical development of the desire component is done. After complete manufacturing of the component the post processing is required which is fifth step where finishing process like cleaning and curing is done and final the component is read to be used.
