Introduction This report will examine the impact of adding two additional diodes to a full-wave rectifier circuit and the overall performance at varying engine speeds. The following sections will review the problem statement, key definitions, and background information, followed by the solution and conclusion. Problem Statement The circuit seen below in Figure 1.1 was provided…
A 2nd Order RLC Circuit incorporate two energy storage elements. An RLC electrical circuit consisting of a resistor (R), an inductor (L), and a capacitor (C) arranged either in series or in parallel. The circuit’s name originates from the letters used to its constituent the three components. These circuits are described by a second-order differential…
Background and Theory This laboratory investigates how the drag coefficient changes with respect to Reynolds number Cd(Re) for two wing types commonly found on aircraft, slightly swept wing and the elliptical wing. A model plane was placed in a wind tunnel which carefully controls and monitors the airflow so the forces/pressure acting on the plane…
Abstract: This laboratory investigates how the drag coefficient changes with respect to Reynolds number Cd(Re) for a smooth sphere and a sphere with bumps. The bumps on the sphere were modeled by adding a rubber band on the sphere. The sphere was placed in a wind tunnel which carefully controls and monitors the airflow so…
Abstract: The purpose of this lab was to determine the effect of stirring and the hot water flow rate on the overall heat transfer coefficient. Based on the law of thermodynamics heat always travels from hot to cold but the rate of heat transfer is expected to be enhanced by the introduction of stirring. During…
Abstract The purpose of this lab was to determine the thermal conductivity k of the disk material by measuring the temperature distribution for transient and steady-state heat conduction in a cylindrical wall. To conduct this experiment cooling water was pumped though the HT10X Heat Transfer service Unit at approximately 1.5 liters/min. Initially the heating power…
Background and Theory This experiment attempts to determine how volumetric flow rate effects changes in head, shaft power and the efficiency of the pump. To simplify this experiment, some assumption/idealizations were made. During this experiment the system is treated as slow speed, steady state with incompressible flow, the pipe and machine walls are solid so…
Background and Theory This experiment looks at how different obstructions affect the force exerted by a water jet. To obstruct the flow of fluid vanes were used. A vane as defined by Webster’s dictionary is “a thin flat or curved object that is rotated about an axis by a flow of fluid or that rotates…
Background and Theory This laboratory aims to recreate the Moody diagram. Moody plotted the Moody Diagram in 1944, and it is now most famous and useful tool in fluid mechanics. The accuracy of the Moody chart is +/- 15 percent [1]. “The Moody Chart gives a good visual summary of laminar and turbulent pipe friction…
Background and Theory This laboratory experiment investigates the surface tension of different working fluids and how contamination can drastically affect surface tension. Surface tension is a result of the molecules deep within the fluid repelling each other while the molecules at the surface attract each other [1]. Introducing contaminates like detergents into the surface of…
