BOILER MOUNTINGS 1.          Blow-Off Cock   The function of blow-off cock is to discharge mud and other sediments deposited in the bottom most part of the water space in the boiler, while boiler is in operation. It can also be used to drain-off boiler water. Hence it is mounted at the lowest part of the boiler. When it is open, water under the pressure rushes out, thus carrying sediments and mud. 2.          Fusible plug It is fitted on the boiler shell directly or through the short branch of pipe at lowest part of the water space.   It consists of gun metal conical plug having a rectangular hole, spindle with yoke. The plug meshes accurately into the similar casing. The plug spindle is generally rotated by mean of spanner on the top of the yoke,   two vertical slots are provided for fixing spanner. When rectangular hole of plug is brought in line ...

High blood pressure or hypertension  High blood pressure is a common condition in which the long-term force of the blood against your artery walls is high enough that it may eventually cause health problems, such as heart disease. Blood pressure is determined both by the amount of blood your heart pumps and the amount of resistance to blood flow in your arteries. The more blood your heart pumps and the narrower your arteries, the higher your blood pressure. You can have high blood pressure (hypertension) for years without any symptoms. Even without symptoms, damage to blood vessels and your heart continues and can be detected. Uncontrolled high blood pressure increases your risk of serious health problems, including heart attack and stroke. High blood pressure generally develops over many years, and it affects nearly everyone eventually. Fortunately, high blood pressure can be easily detected. And once you know you have high blood pressure, you can work with your doctor...

Is your Air Conditioner not cooling properly? Many factors can cause your air conditioning system to resist cooling your rooms, but these are the most common:  Improper Installation Was your air conditioning system recently installed yet it isn’t cooling as it should be? If so, your AC may have been installed incorrectly, or the unit could be too big or too small for your home. Solution:  It is important to get a second HVAC team out to look at your system because the first group did not do something correctly. Unmaintained Condenser Unit One of the most overlooked aspects of AC maintenance is taking care of the condenser outside. Your condenser needs to have good airflow at all times…but it’s outside. That means that weeds and grass are always growing around it. Click here to more detail

  Principles of HVAC System The following factors determine the capacity of HVAC system. Heating : The amount of thermal energy that needs to be added to the space. Cooling : Thermal energy will sometimes need to be removed from a particular space in order to bring the temperature down. Humidifying : The process of increasing the relative humidity through the addition of water vapor into the system. Dehumidifying : Process of removing water vapor from the given space. Cleaning : Purifying the air by the removal of dust, smoke, pollen and other pollutants. Air Movement : Ensuring that there is movement of air to keep the inhabitants comfortable.... more read...

Procedures To begin blood pressure measurement, use a properly sized blood pressure cuff. The length of the cuff's bladder should be at least equal to 80% of the circumference of the upper arm. Wrap the cuff around the upper arm with the cuff's lower edge one inch above the antecubital fossa. Lightly press the stethoscope's bell over the brachial artery just below the cuff's edge. Some health care workers have difficulty using the bell in the antecubital fossa, so we suggest using the bell or the diaphragm to measure the blood pressure. Rapidly inflate the cuff to 180mmHg. Release air from the cuff at a moderate rate (3mm/sec). Listen with the stethoscope and simultaneously observe the sphygmomanometer. The first knocking sound (Korotkoff) is the subject's systolic pressure. When the knocking sound disappears, that is the diastolic pressure (such as 120/80). Record the pressure in both arms and note the difference; also record the subject's position (...

Google has started the global roll-out of its new Chat messaging service, which is designed to replace SMS text messages on Android phones. Chat has features such as group texts, videos, typing indicators and read receipts, which are not available when sending SMS texts. Chat will be integrated with the default messages app on Android phones. However, it will be up to mobile operators to enable the service and it does not offer encrypted messages. The new system has been in development for several years, but is now beginning to appear on Android phones.
