pressure in fluid

• what is pressure in fluid

  either liquid or gas
• what does pressure in fluid cause

  force at a right angle to any surface
• work out pressure

  force normal to surface / area of that surface
• pressure measured in

  pascals
• pressure in column liquid calculated by

  height of column x density of liquid x gravitational field strength
• density measured in

  kg/m*3
• partially submerged objects experience greater pressure on bottom surface then top surface

  true
• resultant force acting upwards

  upthrust
• when submerged in water where is the pressure the greatest

  below the object
• for object to float

  upthrust must equal object weight
• for object to sink

  upthrust must be lower then objects weight
