  Home » Top 10 Best Microphones For YouTube In 2020 Reviews Top 10 Best Microphones For YouTube In 2020 Reviews Microphone / By owner of mechanicalkida. One of these is Youtube. We can now all make our own short movies, music videos and do just about anything we wish within the confines of the law and publish it to the world. In context, it must be said that it’s an incredible thing to be able to do, but as with all these things, it is often misused.  Twenty years ago it was unthinkable to be able to do this, but since 2005 it has been possible, and it has spawned many other similar sites. With some, of course, it operates as a business, and therefore good video recordings are required.  There are plenty of great cameras, but so many come with inadequate sound. Therefore, to do it properly and make it sound professional, you will need a quality microphone. There are specialized microphones for Youtube videos. But which one to buy? Don’t worry, we’ll bring you in-depth re...

Air compressor

Image
Q1]. What is air compressor / defined air compressor ? - Air compressor is a machine which sucks low pressure low temperature air from atmosphere and compress it to high pressure high temperature by reciprocating motion of piston or by rotary motion of blade in casing . - it is work absorbing machine driven by external source. There are many industrial uses of this compressed air. Q2]. Industrial and commercial uses of air compressor ? - for filling the air in tube of vehicle. - for spray painting in Paint industry . - in vehicle to operate air brake. - in automobile service station to clean vehicles. - for cleaning workshop machines.  - for cooling large buildings. -for supercharging of IC engine. - in blast furnace in factory. Q3].classify air compressor?  - Air compressor mainly classified into two groups.  1. Reciprocating air compressor ( positive displacement) . 2. Rotary air compressor.    Classification of reciprocating compressor  1.sin...

SCHMIDT-HARTMANN BOILER

Image
  Type : high pressure ,water tube, forced circulation steam boiler. Working principle : - its principle of working is “ two pressure can be used to effect and interchange of heat energy”. Construction and working: - In the primary circuit, the steam at 100 bar is produced from distilled water. - This is generated steam is passed through a submerged heating coil, which is located in an evaporator drum. -The high pressure steam in this cool possesses Sufficient thermal potential ,due to which, a steam at 60 bar with the heat transfer rate of 10,000 KJ/ metre square-hr degree Celsius  is generated in the evaporation drum.  -The steam produce in the evaporator drum from impure water is further passed through the superheater and then supplied to the prime mover. -The high-pressure condensate formed in the submerged heating coil is circulated through a low pressure feed heater on its way to raise the feed water temperature to its saturation temperature. Therefore, only latent...

VELOX BOILER

Image
  Type :- High pressure, water tube, forced circulation steam boiler.  Working principle : It's principle of working is “when the gas velocity exceed sonic velocity, the heat is transferred from the gas at a much higher rate than rates achieved with sub-sonic flow. The advantage of this theory is taken to effect the large heat transfer from a smaller surface area in this boiler ”. Construction & working : - VELOX boiler makes use of pressurised combustion . - The gas turbine drives the axial flow compressor, which raises the incoming air from atmosphere pressure to furnace pressure.  - The combustion gases after heating the water and steam, flow through the gas turbine to the atmosphere . - The feed water after passing through the economiser is pumped by a water circulating pump to the tube evaporating section.  - Steam separated in steam separating section flow through the superheater and form superheater its move to prime mover. Advantage of VELOX boiler ...
