Product Code : SCL-CELE-14127
The Orifice
and Free Jet Flow Apparatus is designed to study fluid flow measurement
using a sharp-edged orifice under constant head conditions and to investigate
the trajectory profiles of the resultant water jet. This apparatus
allows students to determine the coefficient of discharge (Cd), which is
the ratio of the actual measured flow rate to the theoretical flow rate.
The setup
consists of a vertically mounted transparent cylindrical tank that
maintains a constant head using an adjustable overflow pipe. The
orifice is installed horizontally and flush with the tank wall at the base. The
flow rate (actual discharge) is measured volumetrically using the measuring
tank of an external hydraulic bench. A key feature is the Jet Trajectory
Tracking Device with multiple pins and a plotting board, which allows
students to plot the parabolic path of the free jet for comparison with
theoretical calculations.
