Water from a fire hydrant was used at a pressure of 40 psi to operate the nozzle. The force gauge was mounted in an acrylic box at the same height of the nozzle 22 and 35 feet away. The gauge was wired to a computer to provide data retrieval and storage. Readings were recorded continuous rate of 10 times a second. Several passes of the water stream were allowed to cross the 12"x 12" aluminum plate mounted to the force gauge. After a few minutes, the stream was positioned to directly hit the plate without moving. Data was collect in the units of Newtons and then converted to pounds of force.
The Nozzle used was:
COMPANY PRODUCT
Nozzle MFR M20/2
ANALYTICAL METHODS: Force Measurements-Shimpo Model FGV-50
The data obtained from the force gauge were opened into an Excel file and graphed in Figures 1 and 2. Negative values were obtained throughout the testing. It was determined that when the water stream contacted the plate off center causing the plate to swivel and pull on the force gauge instead of pushing into the instrument.
All three distances have been completed as prescribed by the client.
