Blood flow through an artery is 80 cm3/s. What will the flow be if the radius of the artery is increased by 10%? Assume that neither the pressure across the artery nor the length of the artery changes.

Awater-filled u-tube manometer is used to measure the pressure inside a tank that contains air. the water level in the u-tube on the side that connects to the tank is 5 ft above the base of the tank. the water level in the other side of the u-tube (which is open to the atmosphere) is 2 ft above the base. determine the pressure within the tank.
