For an even quicker figure you can use SI units with this calculation: The roof efficiency ( .8) in liters for every mm of rain on every m 2 of roof. Next steps [edit | edit source] The spreadsheet could be developed to: make best guesses at best tank size; calculate the buyback time depending on cost of the system and cost of water

how to calculate grinding efficiency of a mill PELOT. Grinding efficiency of ball mill calculating equation. Calculation of energy required for grinding in a ball grindingproduct size, p, in a bond ball mill, which is given by the aperture size which passes 80% of the grinding product as a function of the aperture size of the test screen p .

A circular mil (CM) is a unit of circular area with a diameter of one mil (one thouh of an inch). It corresponds to ×104 mm². Where: 1000 CM (circular mils) = 1 MCM or 1 kcmil = mm², so 2 kcmil. It is a unit for referring to the area of a wire with a circular cross section.
