An elephant with a trunk 2.2 m long squirts water (n 1.005 x 10-3 Pa s) at its calf. Inside the trunk are two nostrils that can be modelled as tubes the length of the trunk and with internal diameter 2.3 cm. If water leaves the trunk at a rate of 3.7 litres per second, answer the following. (a) What is the average velocity of the water inside the trunk? m/s = (b) What pressure is the elephant applying to squirt the water? Pa (c) How would the pressure change if the elephant were squirting runny honey (n 5 Pas)? MPa
