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.

The bodies used in the experiments have strong steel hooks for attachment to the suspension cords. The length of the cords can be rapidly changed and securely fixed using clamping wheels. The model permits oscillations on pendulums with bifilar or trifilar suspension to be investigated. The beam can oscillate, by translation, in the plane of suspension like an ideal mathematical pendulum. The cylinder and the circular ring work as rotary pendulums. For this purpose a bar, a cylinder, or a hollow cylinder made of galvanised steel can be hung from a wall mounted carrier plate made of aluminium and placed in oscillation.

A flywheel mounted in ball bearings is placed in motion by a weight attached to a pulley. The inertia of the flywheel can be determined from the fall time of the weight. Using the basic experiments on uniformly accelerated angular motion can be performed. The unit is intended for wall mounting. Due to the clear, robust construction the unit is excellently suited to student experiments.

The rotor is held on the base frame with pivoting bearings. The weights and bearings can be placed at any location along the shaft and attached securely with quick-acting clamps. This benchtop unit is used to show the resonance and critical bending speed on rotating shafts. The construction of the rotor of a thin, flexible shaft and rigid weights facilitates the theoretical comprehension. It is possible to switch speeds during the experiment as desired. A transparent protective hood covers the rotating parts. A set of electrical vibration sensors with clamping set is also available. It is driven by a flexible coupling. Two motor speeds can be fine-adjusted and preset with ten-speed potentiometers. They are controlled electronically and displayed digitally.

This benchtop unit is used to demonstrate the principle of operation of various centrifugal force governors. The centrifugal masses and sleeve forces can be varied using the accessories included. The stroke can be measured using the marks on the governor shaft. When in operation, a transparent protective lid covers the rotating centrifugal governor. The drive with an electronically regulated motor is fitted in the housing. The speed is continuously adjusted using a 10-turn potentiometer and displayed digitally. The governor is placed in a chuck on the drive. The unit can only be placed in operation if the lid is correctly fitted. It only requires a supply of power. The unit is simply placed on a table in the laboratory for operation.

An anodised aluminium disc used as crank is mounted on ball bearings on a white plate. This disc has a pointer so that the input angle can be exactly read on the integrated angle measuring scale. The crank pin can be set at different radii on the disc. The experimental unit is used to generate and investigate pure harmonic reciprocating motion. The slider crank is attached to the crank pin on one side. The model is equipped with plastic feet and is placed on the laboratory table for the experiment. Two handles make the unit easier to carry. On the other side the pin is mounted in straight guide that is fitted with a ruler to allow the output stroke to be read off with precision.

This apparatus enables experiments to be performed on rotational motion in general. The arrangement is fitted to a low friction ball bearing mounted rotating drum. The system is accelerated by a metal weight attached to a cord wrapped around the drum. Weights can be fitted to a rotating rod at marked distances from the centre. A dumb bell-shaped arrangement is thus created; the inertia properties of this arrangement can be changed easily and recalculated. The experiment is set up quickly using table clamps and stands; it is ideally suited to group work for 2-3 persons. The time taken for the weight to fall is measured using a stopwatch, the moment of inertia of the object can then be determined.
