*Resistor starting adds considerable kW load to generator set. Total power required includes the motor kW and the kW which is lost as heat in the resistor.

The series resistors account for a higher than normal starting power factor.

Engine room ventilation can be estimated by the following formulas,assuming 100°F (38°C) ambient air temperature:

V (cfm) = H + Engine Combustion Air0.070 x 0.24 x T

V (m3/min) = H + Engine Combustion Air1.099 x 0.017 x T

V = Ventilation air (cfm) (m3/min).H = Heat radiation (Btu/min) (kW).

T = Permissible temperature rise in engine room (°F) (°C).Density of air at 100°F = 0.070 lb/cu ft (1.099 kg/m3).Specific heat of air = 0.24 Btu/°F (0.017 kW/°C).

Day Tank Sizing

Tank Size (gal) = Rated BSFC (lb/hp•hr) x Rated HP x Load Factor7.076 (lb/gal)

x Hours Between Refilling+ Reserve Requirement

ORRule of Thumb for tank size with 25% reserve0.056 x Ave. BHP demand x Hours between refills x 1.25 = gal.0.27 x Ave. BKW demand x Hours between refills x 1.25 = liters.

Note: Additional tank capacity required for cooling of recirculated fuel in unit injectedengines. Tank should be located below level of injectors or nozzles.

On-Site Power RequirementsBased on 100,000 sq ft. of office bldg., etc and 40°N. Latitudes

• Electric Requirements600 kW continuous load(Air conditioning is absorption)Use three - 300kW units(2 prime and 1 standby)

Refrigeration• One ton refrigeration = 200 Btu/min = 12,000 Btu/h• One Boiler hp = 33,475 Btu/h• One ton compressor rating = One engine hp• Auxilary air conditioning equipment requires 1/4 hp/ton of compressor rating

Ice Plant• Complete power requires 4-5 hp per daily ton capacity

Air Compressor• hp = 1/4 x cu ft m/min at 100 psi

Increase bhp 10% for 125 psiDecrease bhp 10% for 80 psi

FUEL SYSTEM - DIESEL

• Air Conditioning and Compressor400 tons prime loadUse two - 200 hp engines(No Standby)
