DISEO DE TURBINA PELTON

CURSO: TURBOMQUINAS

DOCENTE: ING. PINEDO LUJAN, CESAR FERNANDO

NOMBRE CACHIQUE QUITO CRISTIAN

TRUJILLO PER2014

Algoritmo de diseo:Datos:

H = 200 m (altura)Kp = 0.46 0.95

Q = 3600 m3/h (caudal) 0.98 1.00

n = 600 rpm 0.88 14

Procedimiento de clculo:

Calculo de Z y (d/D): asumimos d/D = 1/10

Redondeamos : se vuelve a calcular d/D

Clculo de

Clculo de n de cucharas:

Potencia real:
