CEE 320 Fluid Mechanics Lab Head Loss Through a Valve April 24‚ 2012 Abstract This experiment determined the relationship between the head loss through a gate valve and the degree of opening of that valve with varying flow rates. The objective of this experiment was to determine the valve loss coefficient‚ K‚ for a specific gate valve as a function of both the pipe Reynolds Number‚ and the degree of opening. The relationship between the Reynolds Number and the friction factor was

add energy to fluid in a system‚ either at the same level or to a new height. There are some fundamental parameters used to determine the performance of a pump. The mass flow rate of fluid is the obvious primary pump performance parameter and for incompressible flow‚ it is more common to use volume flow rate rather than mass flow rate. The performance of a pump is characterized by its net head‚ H. In selecting a pump for a given situation‚ we have a variety of pumps to choose among. The manufacturers

variation in vapor and liquid flow rates on the pressure drop across bubble cap plates is simulated using air and water to represent the vapor and liquid respectively. THEORY: In a pilot tube the relation between the gas velocity and pressure drop is Where‚ is the differential pressure as expressed in the head of the fluid flowing. Where‚ ’=level difference = density of air= 1.21 kg/m3 ’=density of liquid (water) =1000 kg/m3 . Volumetric gas flow rate V (m3/s) is calculated by assuming

SEDIMENTATION According to Brown (1950)‚ sedimentation is the separation of a suspension into a supernatant clear fluid and a rather dense slurry containing a higher concentration of solid. According to Perry ()‚ sedimentation is the partial separation or concentration of suspended solid particles from a liquid by gravity settling. This field may be divided into the functional operations of thickening‚ whose purpose is to increase the concentration of suspended solids in a feed stream; and clarification

several problems which reduce the product quality can occur. Namely‚ water inclusions in the wall‚ severe fingering and double wall defects reduce the product part stiffness. This study investigated the effect of the process parameters water volume flow rate‚ water injection delay time and melt temperature on the part defects to obtain a better understanding of the formation of these part defects. The effect on the residual wall thickness and the weight of the products was also investigated. Three materials

Name: ******** Class: DME2 Title: Flow Measurement Date: 11/02/2013 Lecturer: Mr Higgins Summary: In this experiment many different meters were used to measure fluid flow rate; the orifice plate‚ the venture meter‚ the rota meter and the weigh tank. Each meter works by its ability to alter a certain physical property of the flowing fluid and then allows this alteration to be measured. The measured alterations are linked directly to the flow rate and these measurements are subbed in to
