In the following experiments the local voltage was 212V and then the effective rating is 425V for each element. 6. Readings to be taken from Unit:- 7. Calculations:- Water flow rate constant at: Change of temperature for each power supply (cooling range) = Water inlet temperature, TS - Water outlet temperature, T6 Operations, 3rded.
