Fire tube boiler designing Fire tube boilers operate by sending combustion/flue gas by using a combination of straight tubes flanked by trouble held in identical vessel. Often identified by the variety of passes used (say for example a 3-pass or 4-pass fire tube boiler)‚ this refers to the variety of times combustion gas flows the capacity of the pressure vessel mainly because it transfers heat on the water. A wet-back fire tube boiler utilizes a water cooled publish zone (end closure). A dry-back

endotracheal tube you will prefer RAE‚ flexomettalic or mcintosh? What are the problems associated with these tubes? Ans- Ideal ET Tube is south facing RAE (Ring Adair Elwin) tube fixed in center over the lower lip. RAE Endotracheal Tubes are designed to conveniently position the anesthesia circuit out of the surgical field. Problem- Difficult to pass Suction catheter. Fixed curvature hence more chances of endobronchial intubation or inadvertent extubation. Flexometallic tubes- Inner diameter of tube decreases

I am going to investigate osmosis when potato is placed in different concentrations of sucrose. I am aiming to witness osmosis in 5 different concentrations of sucrose. I will use 5 varying concentrations so that I have a wider spread to compare the results‚ and check that I don’t have any anomalies Prediction Osmosis is the process of diffusion of water molecules from a weaker solution into a stronger solution‚ through a semi permeable membrane. The tiny pores in the membrane

Effects of Different Concentration of Catalyse on Hydrogen Peroxide Aim: In this investigation I will try to find how long it takes for the filter paper disc to rise up whilst varying the amounts of concentration of catalyse. Prediction: I predict that the lower the concentration of catalyse the longer it will take for the filter paper disc to rise to the surface of the tube. Equipment: 1. Hydrogen peroxide in a container 2. Flat bottom tube 3. Tweezers 4. Filter paper

BOURDON TUBE PRESSURE GAUGE Bourdon Tubes are known for its very high range of differential pressure measurement in the range of almost 100‚000 psi (700 MPa). It is an elastic type pressure transducer. The device was invented by Eugene Bourdon in the year 1849. The basic idea behind the device is that‚ cross-sectional tubing when deformed in any way will tend to regain its circular form under the action of pressure. The bourdon pressure gauges used today have a slight elliptical cross-section and

Introduction: This experiment was used to examine the hypothesis that: Osmosis is dependent on the concentrations of the substances involved. Diffusion is the passage of solute molecules from an area of high concentration to an area of low concentration (Campbell & Reece‚ 2005). An example is ammonia diffusing throughout a room. A solute is one of two components in a chemical solution. The solute is the substance dissolved in the solution. The solvent‚ the other component‚ is any liquid in

Direction and concentration gradients Bradley Benton ABSTRACT In this experiment‚ we will investigate the effect of solute concentration on osmosis. A semi‐permeable membrane (dialysis tubing) and sucrose will create an osmotic environment similar to that of a cell. Using different concentrations of sucrose (which is unable to cross the membrane) will allow us to examine the net movement of water across the membrane. INTRODUCTION A major determinant of diffusion in a biological system is membrane

How does Nuclear power work and what happened at Chernobyl? What would you do if your town had a nuclear power plant explosion? Would you help clean up or would you just leave town? I would help the people of my town by cleaning up. The chernobyl explosion was caused by an operator error‚ and cost a lot of money and hurt a lot of people. Nuclear power is made up of atoms that are constructed like a mini solar system. By the late 1950’s nuclear power was developed. There are two types of uranium

tubing and bend the glass tube into a U-shape. The glass tube is then filled with a liquid‚ typically mercury‚ so that all trapped air is removed from the sealed end of the tube. The glass tube is then positioned with the curved region at the bottom. The mercury settles to the bottom After the mercury settles to the bottom of the manometer‚ a vacuum is produced in the sealed tube. The open tube is connected to the system whose pressure is being measured. In the sealed tube‚ there is no gas to exert
