Breathing is something we all do during our life time. We all know we are going to die if we are not breathing. Breathing is a reflex action done by our body to provide the flow of oxygen around the body to the vital organs.


Wikipedia Odell Beckham Jr Jersey , online encyclopedia, describes humans breathe between 12 and 20 times per minute, with children breathing faster than adults.


Babies may breathe as much as 40 times per minute. Adults normally breathe about 500-700ml of air at a time. An average 14 year old takes around 30,000 breaths per day.


However, we can control our breathing. We can be more relaxed by breathing in and out so deeply. The more we allow our body to be filled by deep breathing, the less stress we place on our body and mind.


The more we practice our deep and controlled breathing Bernie Kosar Jersey , the more natural it becomes and we can call on it at any time of day to help us through those tired or stressed out moments.


With all the problems we have -- either we feel stressed out at work, or at the end of a long hard day and we can't sleep, or if we just want a few minutes to our self -- we will find this simple breathing exercise really beneficial.


Here are some steps to do breathing exercise:


1. You can lie down, sit down or stand up as long as you are comfortable. Breathe in slowly through your nose to the count of four. Breathe very deep until all your body feel expanded.


2. Hold on that deep breath for four counts, and then exhale slowly through mouth to a count of eight.


3. Repeat the breathing in ? right down so your tummy expands. Hold on to it and then exhaling nine more times.


4. You can breathe deeper once you get used to the above steps by leave one hand on your stomach and place the other lightly across the chest. Breathe right down so your tummy expands


5. When it can't go any further, breathe in some more and fill the tops of your lungs. Inhalations and exhalation are the same length Austin Seibert Jersey , eight counts each, without holding in between.


6. When you exhales, let the old air out from your chest then from your tummy. So, you are going to be relaxed.


Strengthening a heat exchanger Business Articles | February 15, 2012
Variations in thermal duty and heat transfer conditions, a heat exchanger can be strenghtened simply adding new plates Sheldrick Redwine Jersey , increasing thermal transfer surface area. Quick and easy to satisfy varied project conditions on industrial heat dissipation needs.


A Heat exchanger is an essential thermal machine employed for industrial cooling, with several types existing: shell and tube, plate exchangers, spiral heat exchanger, block and fin heat exchangers. Heat exchangers are crucial equipments for industrial thermoregulation, but also required in residential and commercial air-conditioning plants Sione Takitaki Jersey , achieving heat transfer between two fluids with different temperatures: heat exchangers are indeed passive thermal machines, allowing the transfer of heat energy between fluids, thanks to an existing temperature gap.

In a plate heat exchanger, the fluids are separated by a thin metallic screen, a plate, wich allows the heat transfer between the two fluids flowing on its sides separately. Corrugated plates increase thermal transfer Greedy Williams Jersey , extending exchanging surface area and boosting energy dissipation thanks to turbulence prompted in flowing fluids and higher transmission coefficients.

The cold fluid gets heated in contact with the plate, gaining heat from the fluid to be cooled, and is then carried to a cooling system (a chiller, or dry cooler or evaporative towers, for example), bringing the fluid at a lower temperature.

Plate Heat exchangers offer several advantages Browns Kids Jersey , being compact and smaller, and easily sizable, also to fit new and changed working project conditions leading to a higher thermal duty, with an increased thermal load to be managed. Strengthening a heat exchanger is indeed achieved simply adding new plates, in order to answer a growth in production, and then a growth in the quantity of heat generated Browns Youth Jersey , or due to changes in the thermal conditions of the cooling cycle, for example laking of cooling air or water at a certain temperature, meaning a loss in dissipating capacity of the cooling system itself.

It's plain that is possible to strengthen an existing heat exchanger only in case of an openable and inspectable gasketed exchanger. If a brazed plate exchanger was the first project choice, it won't be possible to increase the thermal load capacity once it is installed, and an alternative solution has to be found to manage an increased thermal duty (adding others exchangers, more powerful or bigger exchangers).

In a plate inspectable heat exchanger is easy to vary the thermodinamic state of the machine Browns Womens Jersey , adding new plates to the existing ones, increasing thermal transfer surface area having extra dissipating capacity. Transfer heat surface area needed to perform the thermal duty in a heat exchanger is usually calculated in function of exchange process characteristics and thermophysical properties of the fluids. Speaking of strengthening an existing heat exchanger, kind of fluids and thermal process are supposed to remain the same, and the only variable is the amount of heat load the machine has to dissipate, or also a new temperature gap between the fluids.

Strengthening a plate heat exchanger is then a quite simple operation, only requiring a correct evaluation of the new thermal load or the new fluids temperatures Black Browns Jersey , in order to determine the right additional thermal transfer surface area and the number of plates that can be inserted to obtain the thermal performance needed.

Strengthening a heat exchanger requires a series of operations, that in the same time allow to check operability and affordability of the exchanger, and in case regenerating it cleaning and changing.
