Provided that the pipe length is 200 m, and the usual geodetic rise is not more than 5 m, this model produces a nominally 40 cubic meters per hour and 400 cubic meters per 10 hours. Sand’s density is 1.3 tonnes per cubic meter, the weight of the extracted sand is 520 tons. extracting Cost 520 tons of sand will be 600 kWh for 10 hours. Nominal diesel fuel consumption for 10 hours is 600 kW x 0.226 l / kW = 135.6 liters. From this calculation, we conclude that to extract 520 tons of sand necessary to 136.6 liters of diesel fuel. production cost of one ton of sand is 136.6 liters / 520 tons = 0.26 liters per tonne.
