EXAMPLE 10.1 The internal and external diameter of the impeller of a centrifugal pump are 300 mm and 600 mm respectively. The pump is running at 1000 r.p.m. The vane angles at inlet and outlet are 200 and 30 ° respectively. The water enters the impeller radially and the velocity of flow is constant. Determine the work done by the impeller per unit weight of water.

A recently built simply supported
RCC roof slab of a single storied
poultry plant in Rawalpindi, collapsed
and killed all the chickens in the
farm. The farm owner blamed the
labor contractor for the defective
work. The contractor denied and
accused the client for providing low
quality and inadequate amount of
steel bars for the roof slab. The farm
owner then asked for compensation
from the steel bar supplier (for
inferior quality bars) and the
consultant (for improper supervision
during construction). The bar
supplier defended herself by saying
that the farm owner bought the
cheapest bar from her which has no
guarantee. The consultant reported
that the cause of the roof collapse is
the use of very dirty water in mixing
the concrete, which was provided by
the farm owner and used by the
contractor despite verbal objections
from the consultant's site supervisor.
