How do you calculate pump head unit in mlc?

To calculate pump head in meters of liquid column (mlc), you can use the formula: Head (m) = (Pressure (Pa) / (Density (kg/m³) × g)) where g is the acceleration due to gravity (approximately 9.81 m/s²). First, convert the pressure from the pump (often given in Pascals) into meters of the liquid being pumped by considering its density. For example, for water, a density of about 1000 kg/m³ is used. The result will give you the pump head in meters, which can be expressed in milliliters of liquid column (mlc) based on the specific liquid's density.
