The water required for 1 m3 of the nominal mix of m20 concrete is about 240 liters, according to math calculations such as 403 × 0.55 = 220 liters. The water concrete ratio is about 0.55 for a normal mix of M20 concrete, so the amount of water needed for a 50kg bag of cement is about 28 liters.

If it is a standard piece of equipment on the neighborhood houses, your chances of recouping the investment are greater. If concrete driveways are not the norm, the return on investment will not be as great.
It takes 2L of water to make 1 kg of concrete. That is approximately 4800L per cubic meter.
how much does concrete cost per square foot
Water weighs more than concrete. Concrete typically has a density of around 150 pounds per cubic foot, while water has a density of 62.4 pounds per cubic foot. This means that water is heavier than concrete for the same volume.
180 ltrs per day
Wet concrete weighs approximately 4,000 pounds per square yard. That amount varies depending on the water content. Lightweight concrete weighs about 1,000 pounds less.
$69 per oz
To do this you would need to know the density of unmixed concrete (i.e what is the weight of concrete per unit of volume), and the ratio of concrete to water required. (I assume you mean 1m^3 of mixed concrete (with water) to kg, rather than the unmixed concrete powder). With these bits of information the conversion is relatively simple, however I don't know where to find this information from. Alternatively, just the density of mixed concrete would suffice.
On average, concrete weighs about 12.5 pounds per square foot per inch thick. This can vary based on the type and density of the concrete mix.
A concrete contractor is paid between $60 and $95 per hour.
