Witryna14 wrz 2024 · What is a good kPa for vacuum? Typical domestic vacuum cleaners can create a suction of 20 kPa. Pascal is a measure of pressure that equals to a pressure of 1 newton of force per square meter of area. 20 kPa would be 20000 N/m2 or around 2 tons per square meter, or around 200 cm (80 inches) of water. Click to see full answer. Witryna14 mar 2009 · kPa, pressure, vacuum I'm a bit confused, kPa is generally thought of as pressure, approx 100 @ sea level. In terms of manifold pressure, at lower load/engine speed, there is more vacuum, so manifold "pressure" is a lower #, (sea level pressure minus the intake vacuum).
