The Piping Loss Apparatus Large is intended to be used with a Hydraulic Bench or an outside water supply. Friction loss is measured by a pressure drop and coefficient of discharge is determined from a pressure drop and a flow rate. Piping Loss Apparatus Large is a comprehensive unit for studying the friction losses in pipes, pipe fittings, and valves and to determine coefficients of discharge for primary flow measuring devices at various flow rates. The pressure drop is measured by differential pressure using manometers. Pressure tapping in by valves with quick connection. All pressure taps are connected by flexible hoses to a set of specially arranged manifolds such that differential pressure across any component can be measured simply by opening valves without removing the hoses. All friction loss components and the flow measuring devices are arranged on a water proof panel which is attached to a floor standing steel frame. Flow rate is obtained from a water meter and a stop watch.

Pumps in a pipe system are used to convert mechanical energy into hydraulic energy this additional energy allows a fluid to move when it is not possible by gravity and for example, to raise a fluid at a certain height above the pump or make it recycle in a closed system. The working principle of a centrifugal pump is based on the fluid inlet in the middle of the impeller, which blades conduct the fluid and thanks to the centrifugal force it is driven outward. In general, the main purpose of a pump in a system is to increase the total energy H. At this point, the fluid is collected and contained by the pump casing which, thanks to its shape, drives the fluid to the outlet pipes or to another impelling stage.
Module For Centrifugal Pump Characteristics is made through a frequency inverter which adjusts the working speed according to each case of study. Module For Centrifugal Pump Characteristics equipment allows the study of the characteristics of a pump working individually at different rotational speeds. These curves can be compared with those supplied by the manufacturer, as well as those obtained by mathematical calculation. The flow measurements are made using volumetric hydraulic of the hydraulic bank (required), that is used also to study the relation between pressure loss and the fluid speed. In addition, the flow control valve manages the pump operating mode in order to obtain experimental operating curves.
The dial gauge can be used to set the upper dead centreexactly on the timing wheel, and thus determine all other piston positions. The engine can be turned easily.
