What reading level is Proceedings of the Annual Convention 37 (1936) book?
To quickly assess the difficulty of the text, read a short excerpt:
Manufacturers of centrifugal pumps are able to so vary the design of the impeller and casing as to produce efficiencies as high as 90 per cent under widely varying heads.
388 Water Service, Fire Protection and Sanitation ADVANTAGES OF CENTRIFUGAL PUMPS Low initial cost.
Low maintenance cost.
Practically noiseless in operation.
Skilled labor for operation unnecessary.
Failure to open a valve or the sudden closure of the valve on the discharge will not immediately damage the pump.
Minimum floor s...pace required.
The open impeller type is particularly adapted for handling muddy or sandy water with minimum injury to working parts.
Can be used in series more satisfactorily than any other type of pump.
They are non-pulsating and do not cause water hammer.
They are particularly adapted where an electric motor is used as power and auto- matic operation is desired.
DISADVANTAGES OF CENTRIFUGAL PUMPS Must have a comparatively low suction head, preferably not exceeding IS feet.
Require priming.
Will not efficiently operate if a slight amount of air leaks into the suction line or where there is a large variation in the pumping head.
