Question for Topic 4: What determines how fast a river flows Part 1) a Consider the 4 containers below filled to the same height with water. All containers have a tap at the bottom. Select any true statements from the list below. (A) (B) (C) (D) Height of water IOAT Figure 1. Containers filled with water. The pressure inside the containers at the taps is highest for container B. The pressure inside the containers at the taps is highest for container D. The pressure inside the containers at the taps is highest for container C. It's impossible to tell for which container tap the pressure is highest. The pressure inside the containers at the taps is dependent upon atmospheric air pressure at the surface of the water.

Part 2) Blood flowing through veins behaves in a similar way to laminar flow of fluid through pipes. Blood with a viscosity of n = 4.48 mPas and a density of p = 1066 kg/mº flows through a vein with a diameter d = 0.700 mm. Note that the area of a circle is given by A = ap? = 1(!)”. = 7 What is the maximum speed at which the blood can flow through the vein given that the flow remains laminar (Reynold number must remain below 2300)? Umax = m/s Part 3) What volume of blood flows through the vein in 2 minutes at this speed? V = L
