The pressure in Pa is equal to 18 mm Hg times 133 Pa /mm Hg = 2394 Pa. Then set 2394 = ρ g h . Solving for h we get 2394 Pa /(10 m/s² 1000 kg/m³ ) = 0.2394 m.

If you were helping in a blood drive, where would you hang the bag of donated blood?

A nozzle with an area of 0.3 cm² is attached to a garden hose with an area of 1.5 cm². The flow rate through the nozzle is 0.12 L/s.

What is the speed of the water in the hose in cm/s? (1 L= 1000 cm³)

What is the speed of the water in the nozzle in cm/s? (1 L= 1000 cm³)
