Water is moving at a velocity of 2.50 m/s through a hose with an internal diameter of 1.60 cm.

 

(a) What is the flow rate in liters per second? 

 (b) Fluid velocity in this hose's nozzle is 14.0 m/s. What is the nozzle's inside diameter? 

 

2.Plaque builds up on the walls of an artery decreasing its diameter from 1.16 cm to 0.62 cm. If the flow speed is 15.0 cm/s before reaching the region of plaque buildup,

determine the following.

a) speed at which blood is traveling through the plaque-constricted region

(b) pressure change within the plaque-constricted region. (Assume the density of blood is 1050 kg/m³. Be sure to include the appropriate sign with your answer.)
