Calculate Compressor Energy Costs

Energy Costs

Formula:
kW x hrs run x cost /unit power
  motor eff x mech eff x 100
Assumptions: 1 On - load time %  
  2 Off - load time %  
  3 Working weeks per year  
  4 Working days per week  
  5 Motor efficiency on load %  
  6 Motor efficiency off-load %  
  7 Mechanical efficiency on load %  
  8 Mechanical efficiency off load %  
  9 Total kW kW  
  10 Hours per Day  
  11 Cost/unit of Electicity p
