In volute casing the discharge area is more. so as per
bernoulli's principle the pressure must be reduces also
from the basics, pressure = Force/Area. so pressure and
area are inversily proportional. By considering these two
basic rules pressure must be reduces. But in any
centrifugal pump, the pressure is increasing. How the
velocity is converted into pressure. In my view only head
is increases but how the pressure increases?

Answer Posted / sanjog,chaitanya
pressure=force/area cannot be applied for fluid dynamics.Its
valid only for fluid statics.
Actually flow rate is constant.Therefore when area
increases,velocity decreases.According to bernoulli's theorem,
P / ρg + v2/ 2g + z =constant,
If v decreases,pressure increases.
