Reports are to be based on the entire data set. Test Equipment Engine See data on the Toyota 4A-F engine at end of the handout. Therefore, do not be surprised if your results for torque and horsepower are somewhat different. The device has a capacity of 1000 hp. The dynamometer contains one perforated disc, which rotates in a housing between a similar set of perforated stators.
Cold water enters the rotor chamber at the center.
The water is accelerated by the rotating disc and thrown outwards by centrifugal action. From the outer diameter of the rotor chamber inwards, the water forms an annulus that rotates at approximately half the disc speed. Hot water is discharged through a hole located at the bottom of the housing. Power is absorbed through the turbulent motion developed inside the device. The resulting drag acts as a resistance to rotation and tends, with an equal effort, to turn the dynamometer housing.
