The Cavitation demonstration device has an upstream diameter of 16.0mm and a throat diameter 4.5mm.

The pump running the device can produce 1, 2, 3, or 4 feet of total head.

The water temperature was approximately 70⁰F.

With this information, assume the pump is flowing freely through the device. For every listed total head, calculate the flow in the pipe, the pressure and velocity in the pipe upstream of the throat, and the velocity in the pipe at the throat if the pressure in the throat is right at the vapor pressure.
