EXPERIMENT: Pressure drop over a bubble cap plate. AIM : This experiment is conducted in an experimental test ring in which the effect of the 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

built his own within a month‚[5] and greatly improved upon the design in the following year. The purpose of a telescope is not to magnify‚ as commonly thought‚ but to collect light. The larger the telescope’s main light-collecting element‚ whether lens or mirror‚ the more light is collected. Importantly‚ it is the total amount

One hand is placed under this when carrying the microscope. 7. Eyepiece - Contains a lens that magnifies about 10X. You look through this. 8. Fine Adjustment Knob - Moves the stage or body tube for focusing with the high-power objective lens. Focuses for details. 9. Course Adjustment Knob - Moves the body tube or stage for focusing with the low-power objective lens. 10. Objective Lens - Magnifies the object from 4X to 40X. 11. Stage Clips – Hold the slide in place on the stage

Other major types of microscopes are the electron microscope (both the transmission electron microscope and the scanning electron microscope) and the various types of scanning probe microscope. Microscope 1. An optical instrument‚ consisting of a lens‚ or combination of lenses‚ for making an enlarged image of an object which is too minute to be viewed by the naked eye.

images. When using a converging lens‚ it’s helpful to remember these rules of thumb. If the object is very far away‚ the image will be tiny and very close to the focal point. As the object moves towards the lens‚ the image moves out from the focal point‚ growing as it does so. The object and image are exactly the same size when the object is at 2F‚ twice the focal distance from the lens. Moving the object from 2F towards F‚ the image keeps moving out away from the lens‚ and growing‚ until it goes to

accommodation of the eye? Ans. The ability of the eye lens to adjust its focal length‚ so as to clearly focus rays coming from distant as well a near objects on the retina‚ is called the power of accommodation of the eye. Q2. A person with a myopic eye cannot see objects beyond 1.2 m distinctly. What should be the type of the corrective lens used to restore proper vision? Ans. A person with a myopic eye should use a concave lens of focal length 1.2 m so as to restore proper vision

270220141122 INTRODUCTION Humans have sight and hearing limitation. Without any devices‚ our sight and hearing was limited. Objective The objective of learning about the limitation of sight and hearing: ● I have learnt that our hearing and sight has limitation. ● I have learnt that we can overcome the limitation of our sight and hearing by using or wearing technology devices. ● The technology devices have make our lives easier. Limitation Of Sight Our sense of sight has its limitations

toothpick away. 5. Stand a thin glass cover slip on its edge near the drop of dye. 6. Slowly lower the other side of the cover slip until it covers the dye completely. Make sure there are no air bubbles. 7. Make sure the lowest power lens (the shortest lens) is in place over the stage. Place the slide onto the stage of the microscope. 8. Look through the eyepiece and turn the coarse focus knob (the largest knob) until an image comes into focus. It should look like scattered blobs. Move the slide

However‚ if it is still not visible‚ return to the x10 objective lens and use the fine adjustment to ensure the Euglena is as sharply focused as possible. Then‚ use the stage control to re-position the slide so the Euglena is directly in the centre of the lens. Return to the x40 objective lens‚ and the Euglena
