en particular hay 1,200 personas en 200 viviendas.
Demanda Existente
1. Molienda de harina a l/2 kglpersonaldia (max)
= 600 kg. Un molino (disponible de inmediato)
proporcionatia 100 kglhora requiriendo 6 horas
a 3.75 kW.
2. Extraccibn de aceite: el consumo de 112
litrolcabezalmes es equivalente a 20 litros por
dia (16 kg). Con un rendimiento de 30% un
extractor de 3 hp trabajando a una capacidad de
15/kg/hors necesitaria operar- 4 horas al dia.
3. Descascaramiento de arrow: Se asume que el
consumo es de l/4 kgldialcabeza = 300
kg/&a = 460 kg arroz (a la conversion tipica de
65%). Una maquina de 5 hp que procesara 200
kg de arroz por hora, requiere operation por 2 9’2
horas a 3.75 kW.
4. Iiuminacidn Ekctrica: Potential 200 viviendas
x 2 focos @ 40 W x 3 horas didrias = 48 kWh
@W.
Demanda Promotional
1. Suministro domkstico de agua: Para esta villa
se calculo 30 litros por dia. (36,000 litros
elevados a 400 pies a una eficiencia de 75%) en
cuatro horas mediante una bomba a motor de 6
hp = 4.5 kW x 4 horas.
2. Aserradero: Para fabricar cajas de empaque
para frutas, el plan es un aserradero de 5 hp
trabajando seis horas al dia = 6 x 3.75 kW.
3. Irrigacibn par elevacibn: Se requiere u.na
bomba para proporcionar 5 cm de agua sobre
40 hectireas por mes durante seis meses a una
ctida de 60 metros. Este requisito demanda una
Existing Demand
1. Flour grinding at 112 kg/person/day (max) =
630 kg. A 5 hp mill (readily available) would
give 100 kg/hour requiring 6 hours at 3.75
kW.
2. Oil expelling: A consumption of 112
liter/head month is equivalent to 20 liters/day
total (16 kg). At 30% yield a 3 hp expeller
processing at 15 hglhr will be required 4
hours/day.
3. Rice hulling: Consumption assumed to be
114 kg/day/head = 300 kg/day = 460 kg pad-
dy (at typical conversion rate of 65%.) A 5 hp
machine will process 200 kg paddy/hour,
requirement is 2 314 hours at 3.75 kW.
4. Electric lighting: Potential 200 households x
2 bulbs at 40 W x 3 hours/day = 48 kWh
(max).
Promotion Demand
1. Domestic water supply: For this village 30
liters/day was assumed (36,000 liters lifted
400 foot at 75% efficiency) in four hours
from a 6 hp pump motor = 4.5 kW x 4 hours.
2. Saw milling: For manufacturing fruit packing
cases a 5 hp sawmill is planned for 6 hour/
day = 6 x 3.75 kW.
3. Lift irrigation: Pumping is required to give 5
cm of water over 40 hectares per month for
6 months at 60 meters head. This will require
a 20 hp pump = 15 kW for 12 hours per day
operation, 6 months of the year. Irrigation
pumping could alternatively be done by
direct mechanical drive using water fed from
the headrace, with the generator being
driven simultaneously.
No attempt has been made to substitute elec-
tricity for cooking in this project, because cur-
rently there is no very cheap electric heat storage
cooker available and, if there were, the price of
electricity would have to be considerably lower or
the cost of firewood and cow dung considerably
higher before it would become an acceptable
alternative. This is very significant because (as
seen in Table 1) it is estimated that cooking
accounts for 66% of Indian villagers’ energy con-
sumption compared with 20% for agriculture and
7% for manufacturing (e.g. brickmaking and pot-
tery). The high consumption for cooking is partly
due to the very low efficiency of traditional
stoves.
