1. Water is pumped into a storage tank from a well delivering 20.0 gallons of water in 30.0 seconds through a pipe of 1.00-in.2 cross-sectional area. What is the average velocity of the water in the pipe as the water is pumped from the well?
2. (a) Calculate the mass flow rate (in grams per second) of blood (ρ = 1.0 g/cm3) in an aorta with a cross sectional area of 2.0 cm2 if the flow speed is 40 cm/s.
(b) Assume that the aorta branches to form a large number of capillaries with a combined cross-sectional area of 3.0 × 103 cm2. What is the flow speed in the capillaries?
