In intravenous feeding, a needle is inserted in a vein in the patient’s arm and a tube leads from the needle to the reservoir of fluid (whose density is 1045 kg/m3) located at the height h above the arm. The top of the reservoir is open to the air. If the gauge pressure inside the vein is 6000 Pascals, what is the minimum value of h that allows fluid to enter the vein? Assume the needle diameter is large enough that you can ignore the fluid’s viscosity.

- Problem 3: A person walks around in high-heeled shoes. Their weight is momentarily placed on one heel which has an area of 1.5 cm². If their mass is 60 kg, what is the pressure exerted by their heel on the floor in pascals?You come across an open container that is filled with two liquids. Since the two liquids have different densities, there is a distinct separation between them. Water, which has a density of ρw=1.00×103 kg/m3, fills the lower portion of the container to a depth of 0.215 m. The fluid that is floating on top of the water is 0.335 m deep. If the absolute pressure on the bottom of the container is 1.049×105 Pa, what is the density, ρl, of the unknown fluid?

The density of glycerine is 1.26×103 kg/m3.You come across an open container that is filled with two liquids. Since the two liquids have different densities, there is a distinct separation between them. Water, which has a density of pw = 1.00 x 10° kg/m², fills the lower portion of the container to a depth of 0.206 m. The fluid that is floating on top of the water is 0.314 m deep.
