Experiment #3 Venturi Meter Fluid Mechanics Lab Abstract Flow rate is a common measurement which often needs to be performed. A venturi meter allows the flow rate in a pipe to be determined from a pressure differential. A venturi narrows the diameter of the pipe for a short duration, converting pressure head to velocity head. Through this pressure differential, Bernoulli’s equation, and the known dimensions of the venturi, the flow rate of the incompressible fluid can be determined. I

IDENTIFICATION OF PATHOGENIC BACTERIA ASSOCIATES WITH WILT DISEASE OF TOMATO By Anam Nawaz Chapter No: 1 INTRODUCTION Occurrence of Disease in a Host due to Pathogen can only happen in the presence of conducive Environment, or in other words “ disease causal are only the combination of these three elements, Susceptible Host, Virulent Pathogen and Conducive Environment. Otherwise disease does not happen. So these three elements was taken into more consideration which are

INTRODUCTION The rapid expansion and increasing sophistication of the chemical industries in the past century and particularly over the last thirty years has meant that there has been an increasing amount and complexity of toxic waste effluents. Even though policies and environmental efforts should continue to be directed towards applying pressure to industry to reduce toxic waste production, biotechnology presents opportunities to detoxify industrial effluents. Bacteria can be altered to produce

Started with 2 slants of nutrient agar and 2 slants of nutrient broth. 1 agar Petri dish. # 11 We inoculated nutrient agar using the needle by one streak from bottom to top. Broth was inoculated as well. One slant and one broth incubated at 25 C and other slant and broth at 37 C. Purpose 1… To determine optimum temp for bacteria Purpose 2… To start collecting morphological characteristics of colonial growth of the bacteria. Color of bacteria in Petri dish is yellowish beige. There are numerous

Subject: Converging-diverging nozzle experiment In this experiment, we used manometers to measure the pressures in the nozzle relative to atmospheric pressure. A water manometer is connected to the inlet pressure tap (P0-P1) and also connected to the throat (P0-P2) and downstream (P0-P3) pressure taps as well. To start this lab we adjusted the flow rate to increase (P0-P3) in equal steps of 2.5 inches of water until the nozzle is choked, which means there is no further increases in (P0-P2) and

in selected piping arrangements. These include sudden expansions, sudden contractions and bends. Other flow components to be studied in this lab include a Venturi flow meter and an Orifice flow meter. The theory for using Venturi tubes and orifice plates for flow rate measurement will also be verified. The hydraulics bench can be operated in both the laminar flow (Re < 2300) and turbulent flow regimes by adjustment of the fluid velocity. At low flows, the velocity is controlled by maintaining level

3 Basic plate count techniques for the enumeration of microorganisms 3.1 Introduction Most of the recommendations and guidelines contained in this chapter are taken from American Public Health Association (APHA), as described in the Chapter 6 of the 4th Edition of the Compendium of Methods for the Microbiological Examination of Foods (Swanson et al., 2001). When different from or complementary to those of the Compendium, they were complemented with information and recommendations from

INTRODUCTION Rationale of the Study Fusarium proliferatum is known as the conidial stage of Giberellafujikuroi, which is an ascomycetous seed-borne fungus that causes bakanae, a disease that influences rice (Nelson, 1994). There are over 100 species of the genus, Fusarium, and they are most common in tropical and subtropical areas. The presence of pathogenic conidia may cause the discoloration in kernels. F. proliferatum is a filamentous fungus or mould found in aerobiologic surveys worldwide.

EXPERIMENT 3 GROUP B AIM: To find the overall efficiency of plate column operating under total reflux, for a binary system (iso-propanol & n- propanol). APPARATUS: * Distillation Column with reboiler * Automatic digital refractometer * Two fluids with different volatilities. PROCEDURE: * Distillation column was filled with the two fluids. * Then we switched on the heater and set the temperature to 126.6 ̊C * And then we allow the system to reach the equilibrium.
