Rotameter Head Loss Experiment
Figure 1: Experimental Setup
Overview
A rotameter can be included between the alum stock tank and the constant head tank in the dose controller to verify the flow rate of chemical. The head loss through the rotameter needs to be determined in order to perform an accurate energy balance on the dose controller to provide precise dosing.
Experimental Setup
The head loss through the rotameter will be determined using a setup similar to the clogging experiment. There will be a pump circulating the fluid, an attentutor to reduce the pulses from the pump, and pressure sensors before and after the rotameter.
The head loss will be determined by performing an energy balance around the rotameter. The pressure sensor readings and the height difference between the inlet and outlet of the rotameter will be used to find the energy loss.
