All air compressors have one issue. A moisture inside the tank accrues that cause rust. Luckily, this air compressor has a ball drain valve. This component is easy in use. You have just to control the air filter and replace it after 5000 hours.
• The operation of the nozzle under choked or unchokedcondition also influences the matching. • The similarity between the flow characteristic of a nozzle and a turbine is the fact that thermodynamically, both are flow expanders. • The matching between the turbine and the nozzle is identical to that between a free-turbine / power-turbine and the main turbine. • Once the nozzle is choked, the nozzle non-dimensional flow will reach its maximum value and will become independent of the nozzle pressure ratio
CAVITATION IN MARINE CENTRIFUGAL PUMPS AND PIPES In a centrifugal pump during its operation the fluid that enters is accelerated by the impeller. At impeller the pressure lowers as the velocity increases (Bernoulli equation). The flow area at the eye of the impeller is usually smaller than either the flow area of the pump suction piping or the flow area through the impeller vanes. When the flowing liquid passes from the eye of the impeller the area that is smaller results in the increase of the velocity followed by the decrease of the pressure. If pressure is lower and/or the temperature is higher than the saturation pressure/temperature some fluid changes to vapour forming tiny bubbles.
In a reciprocating compressor, gas is compressed by mechanical variation of the volume of space inside the cylinder, by reciprocating motion of the piston. For a cycle of operation, there are two strokes such as, 1) Suction stroke, and 2) Compression stroke As the piston moves down, air is sucked from atmosphere to the cylinder through suction valve (a non-return valve). As piston moves up, air is compressed and at the end of compression stroke, air is delivered through delivery valve (which is also a non-return valve). Topmost portion the piston can travel inside the cylinder is is called Top Dead Centre (TDC), and bottom most portion the piston can reach inside the cylinder is called as Bottom Dead Centre
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.

In this work rocket nozzle designed using CATIA software. Due to high temperature from nozzle
It consists of two terminals in which the starting the running terminal of the compressor is connected. As the current enter the capacitor from the second line of the source, the store energy will be released into the starting terminal and activates the starting winding. Every capacitor has different capacity depending on the electric motor where it is being used with. There are two types of capacitor namely mono capacitor and dual capacitor. Fan capacitor, running capacitor and starting capacitor are mono capacitor because they have two terminals for starting and running.
The sucked atmospheric air is compressed into the Compression Cylinder and then it is sent to the Power Cylinder. The system through which the compressed air is transferred to the Power Cylinder is known as Crossover Passage. The compressed air is then mixed with injected fuel and the combustion takes places in the Power
