PROJECT TITLE: Bernoulli’s Principle Aim: To demonstrate Bernoulli’s Principle. Materials Required: 1. Drawing pin 2. Cardboard piece 3. Cotton reel Procedure: Insert a drawing pin through the centre of a cardboard piece and place a cotton reel over the point of the pin. Then hold the cotton reel in one hand and the card in the other‚ and blow air downward or upward through it and release the card. The cardboard

EXPERIMENT (4) FLOW MEASUREMENT By: Eng. Motasem M. Abushaban. Eng. Fedaa M. Fayyad. PURPOSE: To study some of the famous instruments used in flow measurements. The measurement of water flow rate is an important topic in the study of fluid dynamics. There are many instruments used in flow measurements such as : o Venturi o Orifice plate o Variable area meter DESCRIPTION OF APPARATUS Water Flow Measuring Apparatus is designed as a free-standing apparatus for use on the Hydraulics

review the simplest one-dimensional flow equations for horizontal flow of one fluid‚ and look at analytical and numerical solutions of pressure as function of position and time. These equations are derived using the continuity equation‚ Darcy’s equation‚ and compressibility definitions for rock and fluid‚ assuming constant permeability and viscosity. They are the simplest equations we can have‚ which involve transient fluid flow inside the reservoir. Linear flow Consider a simple horizontal slab

be necessary to know genetic makeup of child before birth to prevent abnormal cases. To overcome this problem‚ detection of chromosomal abnormalities in feotus has been introduced. By studying prenatally‚ (before birth with the help of amniotic fluid and chorionic villus) we can prepare genetic makeup‚ i.e. karyotype) to determine whether the fetus has certain abnormalities‚ including certain hereditary or spontaneous genetic disorders. So‚ with use of this technique if‚ any abnormality detect

1.0 SUMMARY: The reactor test rig (RTR) experiment is purposely done to compare the performance of single stage CSTR‚ 3-stages CSTRs and PFR. The solutions that been used in this experiment is dilution of 0.1M of sodium hydroxide‚ NaOH and 0.1M of ethyl acetate‚ Et(Ac) to 60L. There are four common measures of reactor performance and the most important one is conversion. Then the speed is set to be at 300rpm and reading is taken every 5 minutes till the outlet conductivity remains constant. From
