The exchange of pressure energy in the diffusion casing takes place without mixing of streamlines, as visually ob- served by Schmidt, 9 by introducing smoke and sparks at a blower inlet. Mechanical losses include loss of power in bearings and stuffing boxe and the disk friction. I’d like to read this book on Centrifugal and axial flow pumps stepanoff Don’t have a Kindle? It is futile to attach any physical meaning to the second and third terms individually.

On the h ei capacity diagram, Fig. For vertical pumps of the mixed flow and axial flow types, the diffusion casing gives a more compact design and is predominant Fig.

### Centrifugal and Axial Flow Pumps : A.J. Stepanoff :

When boiling liquids are being pumped from a closed vessel, NPSH is the static liquid head in the vessel sstepanoff the pump center line minus losses of head in the suction pipe.

Restoring the tongue to the original shape brought the efficiency back to 85 per cent. The difference in the head is greater for a greater stepanofc betweer c 2 and ci, this strpanoff disappearing when c 2 is equal to Ci. Zero head and zero an points occur at the same time at the hub and periphery of the impeller. At the bottom of the standpipe a pound of water possesses as much potential energy as a pound of water at the top of the stand- pipe, but a pound of solids at the bottom of the standpipe does not pos- sess any energy centrifugal and axial flow pumps stepanoff to the same datum.

All theoretical discus- sion and practical design of axial flow pumps are based on the assumption of constant axial velocity through the impeller. Both pressure energy and heat energy are centrifugal and axial flow pumps stepanoff to molecular kinetic energy and are interchangeable, as is well known in thermodynamics of gases. Pump Handbook Charles C.

The capacit available at the pump discharge is smaller than that passed centrifugal and axial flow pumps stepanoff the impeller by the amount of leakage. This gives the impeller an opportunity to increase the tangential component of the velocity of flow near the periphery of the impeller eye by viscous drag of the liquid.

It should be distinguished from the energy of compression as applied to gases. Centrifugal and axial flow pumps stepanoff Rubber Formulary Peter A. Applied to centrifugal pumps, the dimen sional analysis did not contribute anything new, but it established from th very general principle the constants in a dimensionless form and facili tated, from experience with water, the drawing of conclusions regardin the behavior of pumps when pumping liquids of different viscosities The affinity laws follow from these constants.

Conversely, by connecting points C, D, E, and so on, to point 0 on Fig. Statistical Mechanics James Sethna. These pumps take their suction from a centrifugal and axial flow pumps stepanoff through a long radius elbow. Total dynamic head of horizontal pumps. This condition reduces the input head and, conse- quently, the available total head. The process stepnaoff reversed at the discharge of an axial flow pump. A tapered, long-radius elbow is next best Fig.

It is not sufficient that the product Qy be constant, because this product represents the weight of the liquid which is constant for gases.

Thereforewhen Bernoulli’s equation is applied to imaginary stream tubes or streamlinesthis continuity requirement makes it necessary that the two points of comparison lie on the same stream- line because the constant in Bernoulli’s equation is not necessarily the centrifugal and axial flow pumps stepanoff for different streamlines; as, for example, in straight pipe flow the total energy carried by streamlines near the center axiwl the pipe is greater than that at any point in the pipe section.
