DESCRIPTION
Water is discharged vertically through a nozzle to strike a target carried on a stem, which extends through the cover. The dead weight of the moving parts are counterbalanced by a compression spring. The vertical force exerted on the target plate is measured by adding the weights supplied to the weight pan.
The apparatus consists of a cylindrical clear acrylic fabrication with provision for levelling. Water is fed through a nozzle and discharged vertically to strike a target carried on a stem, which extends through the cover. A weight carrier is mounted on the upper end of the stem.
The dead weight of the moving parts is counterbalanced by a compression spring. The vertical force exerted on the target plate is measured by adding the weights supplied to the weight pan until the mark on the weight pan corresponds with the level gauge.
A total of eight targets are provided.
