Hot-water House Boiler: Heat-Rate Arithmetic and AFUE Limits | FIRGELLI
Compare heat-input and output scenarios with assumed constant efficiencies. Learn why AFUE is an annual measure and this calculator cannot determine boiler size or capacity.
Hydraulic Irrigation: Head, Flow Share and Energy Calculator | FIRGELLI
Compare drive head and delivery lift using an assumed hydraulic-ram efficiency. Results give idealized flow shares and static freshwater pressure, not pump capacity or site...
Internal Worm Wheel: Ratio and Assumed-Efficiency Calculator | FIRGELLI
Calculate an ideal worm-input reduction, wheel speed, torque and power loss using an entered efficiency. Physical contact and self-locking are not determined.
