Calibrating pressure gauges: The cylinder of the pressure gauge unit is loaded with weight support. There are some steps to cunduct the operation: 1. Unscrew pressure relief knob 2. Press down weight support 3. Screw in pressure relief knob Firstly, press down the hand lever while lifting the cylinder gradually with weight support up to the moment it floats on the oil with sufficient guidance.
• Create the Basic Clamping Device: Take the two 30 mm angled pieces. One piece will be used as the top of the clamp, while the other piece will be the bottom. The top piece should be placed as a turned ‘L’, while the bottom piece should be placed on its edge, resembling a ‘V’ shape. Take the top piece, and cut out a small square or rectangular space at the center of its bottom angle. Drill two holes at the ends of it.
Fundus Camera Reticle Setup (Mydriatic) An often overlooked and critical step in obtaining sharp images is to set your reticle. The reticle is the adjustable viewfinder crosshairs and is unique to each operator’s eye visual acuity. To adjust, place a white piece of paper in front of the camera (alternatively, you can use the camera lens cap on), raise the illumination light to highest and while looking through the viewfinder, turn the eyepiece clockwise and counter-clockwise until crosshairs are sharpest. You are now setup. Fundus Photography (FP) To begin, it is standard to start all Fundus photography with the right eye (OD) followed by the left eye (OS).
Gear shaving is basically a low pressure, free-cutting process. A helical gear-like cutter with closely spaced grooves extending from the tip to the root of each tooth, rotates with gear in close mesh in both directions during the shaving cycle. The centre distance between the gear and the cutter is reduced in small controlled steps to remove metal from the gear tooth surfaces till the final required size is achieved. The helix of the cutter is different from that of the gear to be shaved. Fig: Meshing of a Gear with a Shaving Cutter For effective shaving, a pre-determined crossed-axes angle between the axes of the cutter and gear is important.
Extend the tangents from the ZSV region and compression region and bisect the angle formed to locate point 1; 3. Draw a tangent to the curve at point 1; 4. Mass balance Cu.Hu = Co.Ho,(Cu, Co and HO are known): 5. Draw a horizontal line from Hu until it intersects with the tangent line and determine tu; 6. Determine the area required for thickening (At): At = 1.5 (Q+R) tu/Ho Where: Q = flowrate to the aeration tank excluding the recycle
1. Experiment, relationships, & Explanations: 1.1. Phenomenon under study • Newton’s Third Law of Motion • Pressure 1.2. Hypothesis or hypotheses • Allia: My hypothesis is that after I let go of the carton and remove my hand that is covering the bottom holes that one, the water will begin to flow out of the holes. But second, because of the precise and specific placements of the holes, the water coming out of each hole will cause the carton to being spinning in a counter clockwise motion as the water is being released from the holes.
Insert the bit until the shank reaches the bottom of the collet, back it out about 1/16" to 1/8" and then tighten the collet. • Make sure the bits are sharp, smooth and clean Sharp and clean bits help the operation run smoothly and produce good results in a safe way. Dull bits result i a lot of tear-out, not precise cuts. Remember to clean up resin buildup and remove small nicks in the cutting edges for optimal
3.1.2 Pros and Cons • The simplicity of dip coating method lends it to automation. The thickness of the film is determined by the viscosity of the solution and rate at which the substrate is withdrawn from the tank. There are different sizes and shapes of dip tanks so as to accommodate the big object to be
Centrifugal pumps are known to change the Kinetic energy to hydrodynamic energy. Through various calculations we were able to calculate measurements like the suction side length, height of the tank, K-values which were used to read the bends and fittings and the diameter of the pump. The system curves where plotted after obtaining all the required calculations and overall these helped us verify that the results are correct as they follow on the steps of the theoretical
