2) CALCULO DEL SALTO '' H ''

2.1) calculo de la demanda Potencial (Dp)

De la tabla

POBLACION (HABITANTES)DEMANDA DE POTENCIA500 - 100015 Kw - 35 Kw1000 - 200035 Kw - 80 Kw2000 - 400080 Kw - 180 Kw4000 - 10000180 Kw - 500 Kw10000 - 20000500 Kw - 1200 Kw

Dp = 1584Kw(Ver Justificacin)

2.2) Calculo de la demanda Futura Df

Dp = Demanda Potencial Razon de crecimiento promedio anual de la demanda de energia Tiemo de retorno

Df =3356.93Kwtrabajamos:Df = Pot=3357Kw

2.3) Clculo del Salto HDe acuerdo con la expresin de potencia de un aprovechamiento hidroenergtico.

P=9.81 x Q x H x nn=50%

Remplazando Valores tenemos: H=913m Hdisponible913m

2.4) Clculo del Caudal segn la topografa con la que se cuentaSi colocamos Hdisponible para calcular el caudal necesario

Q = P/ (9.81 x H x n)

Q=0.75m3/s
