  3. Cost of transport - Wikipedia

    en.wikipedia.org/wiki/Cost_of_transport

    The metabolic cost of transport includes the basal metabolic cost of maintaining bodily function, and so goes to infinity as speed goes to zero. [1] A human achieves the lowest cost of transport when walking at about 6 kilometres per hour (3.7 mph), at which speed a person of 70 kilograms (150 lb) has a metabolic rate of about 450 watts. [1]

    = 10 parts per million by volume = 10 ppmv = 10 volumes/10 6 volumes NO x molar mass = 46 kg/kmol = 46 g/mol Flow rate of flue gas = 20 cubic metres per minute = 20 m 3 /min The flue gas exits the furnace at 0 °C temperature and 101.325 kPa absolute pressure. The molar volume of a gas at 0 °C temperature and 101.325 kPa is 22.414 m 3 /kmol.

  6. Energy efficiency in transport - Wikipedia

    en.wikipedia.org/wiki/Energy_efficiency_in_transport

    A 68 kg (150 lb) person walking at 4 km/h (2.5 mph) requires approximately 210 kilocalories (880 kJ) of food energy per hour, which is equivalent to 4.55 km/MJ. [ 15 ] 1 US gal (3.8 L) of petrol contains about 114,000 British thermal units (120 MJ) [ 52 ] of energy, so this is approximately equivalent to 360 miles per US gallon (0.65 L/100 km).

    2 is around 0.80 kg (1.8 lb) CO 2 per kg finished cement. Electrical power generation Varies with local power source. Typical electrical energy consumption is on the order of 90–150 kWh per tonne cement, equivalent to 0.09–0.15 kg (0.20–0.33 lb) CO 2 per kg finished cement if the electricity is coal-generated.

  8. Cost distance analysis - Wikipedia

    en.wikipedia.org/wiki/Cost_distance_analysis

    The primary data set used in cost distance analysis is the cost raster, sometimes called the cost-of-passage surface, [9] the friction image, [8] the cost-rate field, or cost surface. In most implementations, this is a raster grid , in which the value of each cell represents the cost (i.e., expended resources, such as time, money, or energy) of ...
