OBD-II is an improvement over OBD-I in both capability and standardization. There is a pin in the connector that provides power for the scan tool from the vehicle battery, which eliminates the need to connect a scan tool to a power source separately. It also provides a candidate list of vehicle parameters to monitor along with how to encode the data for each. However, some technicians might still connect the scan tool to an auxiliary power source to protect data in the unusual event that a vehicle experiences a loss of electrical power due to a malfunction. The OBD-II standard specifies the type of diagnostic connector and its pin out, the electrical signaling protocols available, and the messaging format. Manufacturers may also add custom data parameters to their specific OBD-II implementation, including real-time data requests as well as trouble codes. Finally, the OBD-II standard provides list of standardized DTCs. As a result of this standardization, a single device can query the on-board computer(s) for these parameters in any vehicle. OBD-II Diagnostic Trouble Codes are 4-digit, preceded by a letter: P for engine and transmission (powertrain), B for body, C for chassis, and U for network. Most manufacturers have made the OBD-II Data Link Connector the main connector in the vehicle through which all systems are diagnosed and reprogrammed.

The flow pattern over a notch or weir is complex and there is no analytical solution to the relationship between discharge and head so that once again a semi-empirical approach has to be used. For small scale applications, weirs are often referred to as notches and invariably are sharp edged and manufactured from thin plate material. Hydraulics Bench incorporates a weir channel which is 158mm wide tapering to 152mm wide at the bottom, x 150mm deep x 735mm long in the working surface. The weir channel is fitted with an acrylic 60 triangular notch weir with an integral scale which can be used to provide an approximate indication of the flow rate. In open channels, weirs are commonly used to either regulate or to measure the volumetric flow rate. The Hook Gauge and Scale is an essential accessory for the accurate measurement of the upstream head. They are of particular use in large scale applications such as irrigation schemes, canals and rivers. For a detailed study of the discharge over weirs, provided two sets of weirs and a hook gauge.

A throttle valve makes it possible to regulate the water flow rate. A series of park-away threaded holes along the bottom of the channel (spaced 250 mm apart) allows to fit the optional models. A guide is assembled on the sides of the channel to carry the accessories and the instruments necessary for the tests. The bottom of the channel can be tilted by up to 1.5 degrees, so as to simulate the normal inclinations of the real channels; it is also possible to obtain a slight negative slope. The centrifugal pump draws the water from the collection tank and transfers it to the still tank, where a manually operated vertical gate, which is assembled before the testing section, allows to vary the height of the hydraulic load. The unit is supplied with manuals that describe each component of the system, installation and utilization procedures, and gives many exercises.
The series of channels has been designed by to study the hydrodynamic phenomena of the open surface streams in variable inclination channels. The following versions are available:

The necessity to support the international ship model testing community with the provision of a Podded Propeller Dynamometer has therefore become imperative the need to carry out tests to establish the hydrodynamic and operational advantages of podded drives over conventional propulsion systems is a worldwide requirement and urgent. A variety of podded propulsion drive systems are increasingly being introduced into current and future generation designs of cruise liners, ferries, vessels operating in ice conditions, shuttle tankers and specialist multi-hull vessels.
Features:
The use of a single propeller fitted at either end of the pod or a duel propeller combination rotating in the same direction. The standard gearbox suitable for a Maximum Torque for two propellers 15Nm at each shaft with a combined torque of 30Nm or a single propeller with a max torque of 30Nm
Torque and thrust strain bridge sensor telemetry units available for each propeller (single supplied as standard);
A compact podded propeller dynamometer with driveshaft, bevel gears and two output shafts to which propellers can be fitted if required. Please note the propeller shafts can be designed to suit customers requirements, however in view of the high forces generated within the unit,there is a requirement to use low-mass propellers and not to exceed recommended limits;
Height and Angle Mechanisms: these can be supplied with frame suitable for use in a towing carriage or a mounting system designed to fit the equipment for use with in a cavitation tunnel allowing adjustment in height/depth as well as adjustment in Roll, Yaw and Pitch Angles.
Drive motor and control with speed output signal for data acquisition if required
Combined with an three component balance facilitating measurement of forces drag/unit thrust Fx or lateral force Fly as well as Yaw moment Mz in open water testing
Speed Display Rack: this can be used either with the inline encoder or drive output to display the propeller speed or drive speed.Please note that as the uses a 2:1 gearbox.
The propeller dynamometers are new designs to replace earlier dynamometers only adjustments to the inclination of the propeller shaft could be made, but with the introduction of the adjustment of propeller shaft height can also be achieved. Depending on the maximum capacity of the drive motors, the maximum torque ratings, and consequently the diameters of the propeller shaft ends, are different. The capacity of the drive motors of the same whereas that of less. Apart from the different arrangement possibilities,the technical details of all essential parts of propeller dynamometers are identical, with exception of the capacity of the drive motors and the maximum load ratings in respect of measurement of torque and thrust.

Water turbines are turbomachines utilising water power. The water jet is redirected by approximately 180 in the blades. The impulse of the water jet is transmitted to the Pelton wheel. The Pelton turbine is a type of impulse turbine; such turbines convert the pressure energy of water into kinetic energy entirely in the distributor. During the conversion, the water jet is accelerated in a nozzle and directed onto the blades of the Pelton wheel tangentially.
Learning Objectives And Experiments:
Graphical representation of characteristic curves for torque, power and efficiency
Design and function of a Pelton turbine
Determination of torque, power and efficiency.
