Kenny Rogers - The Gambler

KENNY ROGERS - THE GAMBLER

video

On a warm summers evenin on a train bound for nowhere,

I met up with the gambler; we were both too tired to sleep.

So we took turns a starin out the window at the darknes

stil boredom overtook us, and he began to speak.

He said, son, Ive made a life out of readin peoples faces,

And knowin what their cards were by the way they held their eyes.

So if you dont mind my sayin, I can see youre out of aces.

For a taste of your whiskey Ill give you some advice.

So I handed him my bottle and he drank down my last swallow.

Then he bummed a cigarette and asked me for a light.

And the night got deathly quiet, and his face lost all expression.

Said, if youre gonna play the game, boy, ya gotta learn to play it right.

You got to know when to hold em, know when to fold em,

Know when to walk away and know when to run.

You never count your money when youre sittin at the table.

Therell be time enough for countin when the dealins done.

Now evry gambler knows that the secret to survivin

Is knowin what to throw away and knowing what to keep.

cause every hands a winner and evry hands a loser,

And the best that you can hope for is to die in your sleep.

So when hed finished speakin, he turned back towards the window,

Crushed out his cigarette and faded off to sleep.

And somewhere in the darkness the gambler, he broke even.

But in his final words I found an ace that I could keep.

You got to know when to hold em, know when to fold em,

Know when to walk away and know when to run.

You never count your money when youre sittin at the table.

Therell be time enough for countin when the dealins done.

You got to know when to hold em, know when to fold em,

Know when to walk away and know when to run.

You never count you r money when youre sittin at the table.

Therell be time enough for countin when the dealins done.

CALCULOS PARA COMPRAR AIRE ACONDICIONADO

Para conocer la capacidad del aire acondicionado que se debe comprar para determinado lugar se deben tener en cuenta varios factores como lo son:

  1. Numero de personas que habitaran el recinto.
  2. Numero de aparatos que se encuentran en el lugar que disipen calor(computadores televisores, electrodomésticos en general).
  3. Ventilación (posibles fugas de aire que puedan haber como ventanas, puertas, etc)
  4. Área del lugar en metros cúbicos (m³) Largo X Ancho X Alto.

    Para realizar el cálculo de capacidad se debe tener en cuenta lo siguiente:

    12.000 BTU/h = 1 TON. DE REFRIGERACION
    1 BTU/h = 0,252 Kcal/h
    1KCal/h = 3,967 BTU/h
    1KW = 860 Kcal/h
    1HP = 642 Kcal/h
CALCULO DE CAPACIDAD
C = 230 x V + (# PyE x 476)
DONDE:
230 = Factor calculado para America Latina "Temp máxima de 40°C" (dado en BTU/hm³)
V = Volumen del AREA donde se instalará el equipo, Largo x Alto x Ancho en metros cúbicos m³
# PyE = # de personas + Electrodometicos instalados en el area
476 = Factores de ganancia y perdida aportados por cada persona y/o electrodoméstico (en BTU/h)
Por ejemplo, para instalar un aire acondicionado en un cuarto de 2,8 m de ancho por 3,5 m de largo y 2 m de altura, donde generalmente van a estar 2 personas, un televisor y un computador.
V = 2,8 x 3,5 x 2 = 19.6 m³
# PyE = 4
C = (230 x 19.6) + (4 x 476)
C = 4508+1904
C = 6412
El equipo Acondicionador de Aire que se requiere debe ser de 7000 BTU
Para el calculo en Frigorias divide el valor en BTU por 3,967
