Answers
1.
To find the total efficiency of the hydronic loop, we need to multiply the efficiency of each device.
Total efficiency = Efficiency of Transformer x Efficiency of Electric Motor x Efficiency of Gears x Efficiency of Pump x Efficiency of Flow Control Valve x Efficiency of Hydronic Piping
Total efficiency = 0.92 x 0.79 x 0.93 x 0.60 x 0.58 x 0.96
Total efficiency = 0.2329 or 23.29%
Therefore, the total efficiency at which water will be circulated in the hydronic loop is approximately 23.29%.
2.
To calculate the efficiency of the transformer, we need to use the formula:
Efficiency = (Transformer Output Power / Electric Meter Output Power) x 100%
Efficiency = (904 W / 994 W) x 100%
Efficiency = 0.9107 x 100%
Efficiency = 91.07%
Therefore, the efficiency of the transformer is approximately 91.07%.
