Water flows through a horizontal tube of diameter 2.8 cm that is joined to a second horizontal tube of diameter 1.6 cm. The pressure difference, P1- P2, between the tubes is 7.5 kPa.
a) Which tube has the higher pressure?
b) Which tube has the higher speed of flow?
c) Find the speed of flow in the first (larger) tube.
d) Find the speed of flow in the second (smaller) tube.
