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?
