Now as the metal disc comes in contact with the rotating flywheel, due to friction the kinetic energy is transferred back to the rear wheel via the chain. Thus the conserved kinetic energy in the flywheel is recovered back to accelerate the cycle after a momentary
Wicket gates around the outside of the turbine's rotating runner control the rate of water flow through the turbine for different power production rates. These openings convert the pressure of the water into momentum just before the water impound on the blades to maintain a constant flow rate. As the water moves through the runner its spinning radius decreases, further acting on the runner. This aspect about the turbine, the water's pressure, assists the Francis Turbine in harnessing water energy efficiently. The fluid enters from the penstock to a spiral casing which completely surrounds the runner.
These pumps use the principle of rotation for moving the fluid. The vacuum is created by the rotary motion which carries the liquid from pump inlet to the outlet. Air is removed in rotary type pumps naturally instead of eliminating it manually. However, if they operate at high speeds, the fluid will cause erosion as the clearance between the rotating pump and the outer edge is close to assist maintain slow and steady rotation. Rotary type pumps are further grouped in three main types: (i) Gear Pumps.
2) Cylinder Heating - The cylinder consists of two parts, the inner cylinder, a stationary assembly in which the heating element are mounted; the outer cylinder, which rotates around the inner cylinder. Pressure Mechanism: Pressure is applied constantly and uniformly right through the process once fed into the machine. Actual pressure is applied at the outlet point where drums put heavy pressure on just heated fusible piece. Time Mechanism: Fusing time is based on the speed of conveyor belt; faster the belt runs, the shorter the time. All machines have speed controller which could be adjusted to give various dwell times in the heated zone.
The chain length was calculated to be 90 pitches. System-level diagram: Functional analysis: The rotors: These are the main mixing elements of the machine and are responsible for the mixing of the raw material which happens between the blades. The shape of these ‘wings’ is very important to ensure smooth fluid flow through the machine. An optimal length to diameter ratio helps mix more efficiently. Mixing quality is also greatly influenced by the speed of the rotors, too fast and the fluid will develop cavities, too slow and the mixing process will be too inefficient.
The concept where gears decrease the speed of the vehicle but increase its torque is called as gear reduction. External Structure The outside structure of a DC geared motor looks as a straight extension over the simple DC motor. The side view of the motor shows the external protrudes of the gear head. A nut shaped metallic ring is placed near the shaft which helps in attaching the motor to the other parts of the assembly. • IC Lm293d IC LM293d is motor driver that is used to drive the motor clockwise or anticlockwise.
A supersonic inlet is made up of two distinct parts. First, the flow is compressed supersonically from the velocity of the flight vehicle or, in other words, the free stream Mach number. This can be achieved by reducing the flow area as the flow proceeds downstream. In this area, the flow velocity is reduced via a series of compression waves and/or oblique shocks. Flow velocity is reduced to a minimum speed at the duct minimum area, also known as the throat of the inlet, where the
Slippage is required between the roller and the ball. at the same high friction must be between the ball and the roller, and between the ball and the floor. the condition of accomplish high and low friction between the ball and the rollers is difficult to achieve. This driving mechanism has disadvantages such as, the asymmetric friction on each driving roller in each plane ‘pushed’ or ‘pulled’ the ball, and ball transfer in this mechanism is required to support the load on the ball’s top which came from ballbot body, and this produces friction increasing on the top of the ball and leads to wear of the ball. Wu and Hwang introduced studies to avoid the problem of asymmetric friction on the ball, by using four omni-wheels to drive the ball, and they named it ‘Combination of Omni-wheel and Spherical Wheel Unit’ or CWWU.
The capacitor is recharged from the DC source through a resistor (Figure 1.2) after each discharge. The successive spark is transferred to the next narrowest gap. The cumulative effect of a succession of sparks spread over the entire work piece surface resulting to its erosion as such this machining process gives to a shape which is more or less similar to that of the
As the hot air is going to the nozzle, it passes through another group of blades called the turbine. The turbine is attached to the same shaft as the compressor. Spinning the turbine causes the compressor to spin. The image below shows how the air flows through the engine. The air goes through the core of the engine as well as around the core.
