A Pelton wheel is to be designed to develop 735.5
kW at 400 r.p.m. It is to be supplied with water
from a reservoir whose level is 250 m above the
wheel through a pipe 900 m long. The pipeline
losses are to be 5 per cent of gross head. The coefficient of friction is 0.005. The bucket speed
is to be 0.46 of the jet speed and efficiency of
wheel is 85%. Calculate :
(i) Pipeline diameter,
(ii) Jet diameter, and
(iii) Wheel diameter

Answer:
The pelvic inlet, or the upper pelvic narrow, is the anatomical limit between the true pelvis below and the false pelvis above. There are tangible, genetic and hormonal differences between the male and female pelvis related to the reproductive function.
In obstetrics, the pelvic inlet is the entrance door toward the birth canal. The fetal cephalic extremity needs to position itself and to adapt adequately to be able to compare the smaller diameter with the largest diameter of the space delimited by the anatomical line of the maternal pelvic inlet.
The shape of the inlet depends on the general shape of the pelvis, according to the traditional classification of Caldwell and Moloy
