Example Design Conditions:
DCOS: 3000 GPM @ 150 TDH Constant speed pump operation Pump A is 86% Efficient at DCOS Pump B is 81% Efficient at DCOS Pump system motor efficiency is set at 95% Power Cost is $.06/KwH Pumping Water with 1.0 Specific Gravity 8000 hours/yr annual pump operation

DCOS:
GPM		Pump A Efficiency at DCOS:	%
TDH		Pump A Brand: (optional)
Pumping Water with Specific Gravity		Pump B Efficiency at DCOS:	%
Motor Efficiency	%	Pump B Brand: (optional)
Power Cost (example: $.06)	/ KwH	Annual Pump Operation	hours/year

Brake Horse Power=	GPM x TDH x SG
	3960 x Pump Efficiency

Pump A	Req. BHP	=	3000 x 150 x 1.0	=
			3960 x 86% Pump Eff

Pump B	Req. BHP	=	3000 x 150 x 1.0	=
			3960 x 81% Pump Eff

Difference in Pump A and Pump B BHP		=	( - )	=
NOTE: Pump B requires 8.2 BHP more than Pump A


Energy Savings =	BHP diff x .746 Kw/BHP x 8000 hrs/yr
	motor efficiency

Therefore Energy Savings=	BHP x .746 KW/BHP x hrs/yr			=	KwH/yr
	% Motor Efficiency

Operating Cost Savings =	KwH/yr	x	$ per KwH	=	per year

Assuming 20 year pump life, the total operating cost savings for selecting the higher efficiency pump is				=
